Question

The volume of a suitcase is 4.2 cubic feet. what is the volume of a suitcase that is smaller by a factor of 0.9? round to the nearest tenth.

Answer 1

The volume would be 0.9 x 4.2

This means it is 90% smaller

Don't forget to round the nearest tenth place. That's the first decimal, so you answer should only have 2 digits.
