Each "whole one" is made of 5 fifths. Therefore 5 whole ones will contain 25 fifths.
There are two because 10/5 = 2
15/5 = 315/5 = 3
five 5.
5 fifths are in a whole (1). 75 fifths are in 15.
15 fifths are in 3- each whole has 5/5 and there are 3 wholes, so 3 x5 = 15 fifths
There are two because 10/5 = 2
15/5 = 315/5 = 3
Twenty fifths is 4 whole.
five 5.

There are: 5

5 fifths are in a whole (1). 75 fifths are in 15.
3 / (1/5) = 3*(5/1) since division by a number is equivalent to multiplication by its inverse = 3*5 = 15
5 of them because 5/5 = 1
15 fifths are in 3- each whole has 5/5 and there are 3 wholes, so 3 x5 = 15 fifths
5 fifths is one whole 5x 4 = 20 fifths = 4 wholes
