Question

correct 89.6162 to two decimal places

Answer 1

Since we are correcting to two decimal places, we would just need the first three decimal places, as it is the third decimal place which will determine the result.
If the third decimal place is 0, 1, 2, 3, or 4, we round it down. If it is 5, 6, 7, 8, or 9, then we round it up. Since the third decimal place is 6, we round 89.6162 up to 89.62.

Answer 2

Algebra defines a decimal number as a number the whole number and fractional number part of which is separated by a dot or decimal.

The answer will be 89.62.

For converting and correcting a number to two decimal places, we need to consider the number at third decimal place.

Rules for correcting decimal number:

• If the number at third decimal place is 1,2,3 or 4, we have to round down second decimal place.

• If the number is 6,7,8,or 9, the rounding should be done upwards.

• Where the third decimal place has 5, rounding can be either upwards or downwards.

In the given question, 6 is at the third decimal place. therefore it needs upward rounding.

Hence the answer is 89.62.
