Question

Estimate the difference of the decimals below by rounding to the nearest whole number. 23.827

- 1 .218​

Answer 1

Explanation:

The key rule is: to round up the number one digit to the left has to be the number 5 or more, else it rounds down.

23.827 rounds up because the 8 is more than 5.

1.218 rounds down because 2 is less than 5.

24-1= 23
