What is 74283.629 to the nearest hundred?

Answer 1

To the nearest hundred, look at the tens column digit (the digit to the right of the hundreds column digit), if it is 5 or more round up otherwise round down.

10s column contains 8, so round up:

74283.629 → 74300 to the nearest hundred.

If you meant the nearest hundredth then look at the thousandths column and apply the rounding rule.

1/1000s column contains 9, so round up

74283.629 → 74283.63 to the nearest hundredth.

Answer 2

To round to the nearest hundred, you will round up if the 10s value is greater than or equal to 50 and round down when it is less than 50.

83 > 50 so you will round up.

Therefore, the value will be 74300 or 7.43 x 10^4 in scientific notation.
