There are times when working with fractions is more convenient than working with decimals.
10 times as big.
Do it multiple times, and check it with a calculator multiple times also
1.053333 repeating times.
something with fractions or decimals
3.266666666666667 times.
Because left of the decimal point goes times 10 for every position and right of the decimal point goes times -10 for every position.

13 x 7
4.7 x 10
About 115 in three significants, no decimals!
