## Suggested Questions And Answer :

### How do you convert a decimal to a fraction?

Count the decimal places then write 1 in front of the same number of zeroes. Example: 0.1234. 4 decimal places so write 10000. Now take away the decimal point and make a fraction: 1234/10000. The fraction reduces: 617/5000. For recurring decimals count the decimal places over which the recurrence occurs and divide by the number made of as many 9's. Example: 0.027027027... The recurring pattern is 027, 3 decimals. 027/999=1/37. For decimals with a recurring section, force the decimal point so that it is immediately in front of the recurring part by counting how many decimal places there are before the recurring pattern. Example: 0.0583333... 3 decimal places before the recurring 3. Now multiply by 1000 (3 zeroes following 1): 58.333... Remember we multiplied by 1000. The recurring part is just one decimal, so we make the fraction 3/9=1/3. The large number is therefore 58 1/3. Convert this to an improper fraction: (3*58+1)/3=175/3. Now divide by the 1000 we multiplied with earlier: 175/3000=7/120.

### what is 0.0000624 rounded to the nearest 10th?

what is 0.0000624 rounded to the nearest 10th? A tenth is 0.1, so to the nearest tenth means to the 1st decimal place. That means that you only consider ths 2nd decimal place. So look at the following value, 0.00  (the 1st two decimal places of the number 0.0000624) If the 2nd decimal place digit is greater than or equal to five, then the 1st decimnal place is rounded up by one, else it is left as it is. Since the 2nd decimal place is zero, then no change is made to the 1st decimal place. So to the nearest tenth 0.0000624 has the valuue 0.0

### 12.09496 to 4 decimal places

Let's try to make it easier for you to understand. In the fourth place of decimals we have the number 9 and next to it 6. Anything above 5 in the 5th decimal place means we need to adjust the 4th decimal place to round up. That means we add 1 to the 9, but because adding 1 makes 10, we have to carry over to the 3rd decimal place making 50. The final result is 12.0950. We can't write 12.095 because we want to show that we've gone the whole hog and produced an answer correct to 4 decimal places, not 3. The final zero confirms accuracy to 4 decimal places.

### How can you change a decimal to a fraction?

You count the number of decimal places and write 1 followed by as many zeroes as there are decimal places. Then you take the figures after the decimal point as a whole number and divide by the number made up of the 1 and zeroes. That's your fraction. Example: 7.3125. 4 decimal places means we create the number 10000. Use this as the denominator: 3125/10000. This cancels down by dividing by 25 top and bottom: 125/400. We can divide further by 25: 5/16. So 7.3125=7 5/16. Another example: 0.0124=124/10000=31/2500.  What about recurring decimals? This time we write a row of 9's with as many 9's as their are recurring portions of the decimal: 0.285714285714285714... The recurring part is 285714 and so we need 6 nines in a row: 999999. We use this as the denominator with the recurring numbers as the numerator: 285714/999999=2/7. Another example: 1.076923. The fraction part is 76923/999999=1/13 and the number is 1 1/13. But what about 0.166666...? The recurring part doesn't start till after the 1. Multiply by 10 to move the decimal point: 1.666666. Now the recurring part is just 6 and the fraction is 6/9=2/3 and the complete number is 1 2/3 which we make into an improper fraction: 5/3. But we need to divide this by 10 because we multiplied by 10 earlier: (5/3)/10=5/30=1/6. Let's try another: 0.041666666... Multiply by 1000 to move the decimal point 3 places: 41.666666... which is 41 2/3=125/3. We now need to divide by 1000: 125/3000=1/24. Example: 7.00333333... Put the 7 aside for a moment. 0.00333333... Multiply by 100: 0.33333... which is 3/9=1/3. Now divide by 100: 1/300, and put the 7 back: 7 1/300.

### How do you convert decimals to percents?

All you do is move the decimal point two places to the right. If there aren't enough places, fill in from the right with zeroes. You will never need more than two zeroes. For example: 1 is 100%; 0.5 is 50%; 0.25 is 25%; 0.1 is 10%; 0.01 is 1%; 0.005 is 0.5%; 1.234 is 123.4%; 0.1234 is 12.34%. If the decimal point is missing as in 1, it's actually to the right but invisible. So 1 is 1. or 1.0 really and when we move the decimal point two places to the right we have to fill in with zeroes: 100%. The decimal point becomes invisible again, because we don't need it. To convert from percent to decimal you do the opposite: move the decimal point two places to the left and fill in with zeroes if necessary, as in 5% which becomes 0.05.

### Expression: 1.7 divided by 4 over 10

4.7/0.4 bekum 4.7*2.5 =11.75

### where do you place the comma seperator in this number .05905

The comma separator applies only to the whole number part. It's not applied to decimal fractions. The decimal fraction simply continues without any further separators after the decimal point (in some countries the decimal point itself is a comma).

### what is 25% of 88

What is 25% of 88? I don't know what you know but I will take it step by step. First of all the word OF MEANS multiplication. So what the question is really asking us to do is this: 25% X 88  = ? The BEST way to solve this is turn 25% into a decimal number. To change ANY percentage to a decimal number move a decimal point LEFT TWO places. In other words do this... 25% = .25    Move decimal from right to left two places. When you do this drop the percentage sign. (There is always a decimal at the end of whole numbers such as: 3 is really 3.0 we don't write it that way because its too confusing. Which I hope I didn't do.)   So again we were asked to do this: 25% X 88  = ? We changed 25% to .25 therefore our new question is What is .25 X 88? 1.  If your doing it on paper. Solve like you would normally with any     multiplication. DON'T worry about the point in .25 YET. Just do 88 X 25 keeping in mind it's there. You will need to know this in a minute.  What ever answer you got. Now move the decimal over two places from the right to left. (There is two places in .25) 2. If you have a calculator you already know the answer to .25 X 88   Is each digit in your answer the same? It should be!

### what is the anwser to this 67.82 divide by 2.8

It's the decimal points that are confusing you, isn't it? There are a number of approaches, but the first thing to do is to move the decimal point in the divisor 2.8. Move it one place to the right to get 28, and move it one place to the right in the dividend to get 678.2. Now you can split 28 into its factors 4 and 7, and divide by one then the other like so:  by 4: 678.2/4=169.55 then by 7: 169.55/7=24.22142857... (Easier to divide by 4 first so that you have a smaller number to divide by 7.) A quick explanation of how you divide the decimal: when dividing 678.2 by 4 you get 169 and you haven't finished because you have 2 to carry and you've just met the decimal point, right? Ignore the decimal point but write the next number in the quotient with a decimal point in front of it and carry on: 169.5. You still have 2 over, so bring down a zero to make it 20 and divide again to get another 5: 169.55. Do the same when you're dividing by 7 and keep bringing down zeroes with each remainder. The number goes on forever, so stop when you have enough decimal places or you get fed up! The other approach is to use long division, bringing in the decimal point as above. Long division will take you longer than splitting into factors because you probably won't know your 28 times table as well as you know your 4 and 7 times tables.
