Answer 1

To round a number to a specific place, look at the number to the right of that place. If the number is less than 5, round down. If it is greater than or equal to 5, round up.

Question 1: 613 rounded to the nearest ten is 610.

The tens digit in 613 is 1. To the right of 1 is 3. Therefore, the approximation of 613 is:

`613\approx610`

THIS STATEMENT IS TRUE.

Question 2: 1,970 rounded to the nearest hundred is 1,900.

The hundreds digit in 1,970 is 9. To the right of 9 is 7. This means that we will round up by adding 1 to 9. Therefore, the approximation will be:

`1970\approx1900+100=2000`

THIS STATEMENT IS FALSE.

Question 3: 54,318 rounded to the nearest thousand is 54,000.

The thousands digit is 4. To the right of 4 is 3. Therefore, the approximation is:

`54318\approx54000`

THIS STATEMENT IS TRUE.

Question 4: 476,022 rounded to the nearest ten thousand is 470,000.

The ten thousands digit is 7. To the right of 7 is 6. This means that we will round up. Therefore, the approximation is:

`476022\approx470000+10000=480000`

THIS STATEMENT IS FALSE.
