Let's solve the problem step by step.
We are asked to
round each decimal to the nearest whole number. To do this, we follow the standard rounding rule:
>
Look at the digit in the tenths place (the first digit after the decimal point):
> - If it is
5 or greater, round
up.
> - If it is
less than 5, round
down.

💡
Tip: When rounding decimals to the nearest whole number, you only need to look at the
tenths place (first digit after the decimal). The hundredths place (second digit) doesn't affect the rounding unless you're rounding to a different place value.

Parent Tip: Review the logic above to help your child master the concept of rounding decimals to the nearest tenth worksheet.
