### what is 0.3 repeating rounded to the nearest thousand

0.3333333333 (3's forever) rounded to the nearest thousand: 0.3333333333 = 0000.33333333333 The left-most 0 is in the thousands place.  The next digit over is the 0 in the hundreds place.  Because that digit (0) is less than 5, the 0 in the thousands place does not round up to 1.  We have a 1 in the thousands place and everything to the right of that just becomes 0s. Result:  0000.333333333 becomes 0000.00000000 or just 0. Answer:  0 . If you meant "round to the nearest thousandth," then: 0.33333333 (3's forever) Counting from the left, the third 3 is in the thousandths place.  One digit to the right, in the ten-thousandths place, is another 3.  Because that digit (3) is less than 5, the 3 in the thousandths place does not round up to 4. Answer:  0.333

### using digits 0-9 only once, what combination of 3 digit numbers add to 1000, one digit will be spare

You have to have 3 sets of 3 digits each.  The first set totals 10 (for the ones place).  The second and third sets total 9 (for the tens and hundreds place).  The 1 carries over from the total of 10 in the ones place, moving the 9 up to 10 in the tens place and the 9 up to 10 in the hundreds place. Ways to make 10: 019, 028, 037, 046, 127, 136, 145, 235 Ways to make 9:  018, 027, 036, 045, 126, 135, 234 If 10 is 019, 9 leaves 234, not enough ways If 10 is 028, 9 leaves 135, not enough ways If 10 is 037, 9 leaves 126, not enough ways If 10 is 046, 9 leaves 135, not enough ways If 10 is 127, 9 leaves 036, 045, enough ways but 036 and 045 share 0 If 10 is 136, 9 leaves 027, 045, enough ways but 027 and 045 share 0 If 10 is 145, 9 leaves 027, 036, enough ways but 027 and 036 share 0 If 10 is 235, 9 leaves 018, not enough ways. We checked all of the possible combinations of 3 digits totaling 10 and it looks like none of them leave any combinations to make two sets of 3 digits totaling 9 each. Answer:  No solution.

### how do you round 49,052 to the nearest thousand?

The 9 is in the thousands place. Look one digit to the right, in the hundreds place. If that digit is 5 or greater, then add 1 to the 9. If that digit is 4 or less, then leave the 9 alone. Replace everything to the right of the 9 with 0s. 0 in the hundreds place. 0 is 4 or less, so leave the 9 alone. Answer:  49,000   If the problem had been to round 49,552 to the nearest thousand, then the 5 in the hundreds place would have made the 9 go up by 1 and the answer would have been 50,000.

### 1.8984375 rounded to the nearest dollar

If the question is "what is \$1.8984375 rounded to the nearest dollar?" then: We're rounding to the ones place.  There's a 1 in the ones place.  The next digit to the right (8) is greater than or equal to 5, so the 1 rounds up. Answer:  \$2 . If we wanted to be super-exact about it, 1.8984375 rounded to the nearest dollar is \$0 because 1.8984375 is not a measure of money.  Your teacher is probably looking for the \$2 version above though.

### How do I find thr greatest place value in a number for a fourth graders math assignment?

The greatest place value in a number is the place value of the digit on the far left. Example: 123.456 The digit on the far left is 1. The 1 is in the hundreds place. The greatest place value in 123.456 is the hundreds place. . Note:  Special Condition:  The greatest place value in a number is the place value of the non-zero digit on the far left. We don't usually write things with 0's on the left (00037 vs. 37), but if we do, the greatest place value in a number is the place value of the digit on the far left, ignoring any 0's to the left of the leftmost non-0 digit. Example: 0007.89 Ignore the 0's on the left 7.89 7 is on the far left 7 is in the ones place The ones place is the greatest place value in 0007.89 . Example: 00012300.456 We only remove the 0's on the far left 12300.456 The far left digit is 1 The 1 is in the ten thousands place The ten thousands place is the greatest place value in 00012300.456

Example: 0007.89 Ignore the 0's on the left 7.89 7 is on the far left 7 is in the ones place The ones place is the greatest place value in 0007.89 . Example: 00012300.456 We only remove the 0's on the far left 12300.456 The far left digit is 1 The 1 is in the ten thousands place The ten thousands place is the greatest place value in 00012300.456

### Need eight digit combination using 1,2,9,0,1,0,0,0. How many possible combinations?

If by combinations you mean as in a safe, it's permutations of those digits you want isn't it? If all the numbers were different, the answer would be 8 factorial (8!), which is 8*7*6*5*4*3*2*1 = 40,320. However, you've got some duplicate digits. So we have to reduce this number by the number of permutations we've "lost". That's 4! (24) for the four zeroes and 2! (2) for the two 1's. That leaves us with 840 when we divide by 48. The same answer would apply of course for any digits similarly duplicated. If asked by the police, I shall of course deny all knowledge!

### what is 3.984 rounded to 1 decimal place

Since you need to round 3.984 to one decimal place, then that will be to the nearest tenth which 9. But the # at the right of 9 is 8, so it will be added by 1... 9 + 1 = 10 which is a 2-digit #, the 1 should be added now to 3, and what remains in the tenth digit is 0. 3.984 = 4.0 (final answer)
