Samuel measured three ropes as 3and 63/80 feet, 3and 1/5 feet, and 3and 11/20feet. put the measurements of the ropes in order from lease to greatest.

The measurements in the order given are:
3 63/80, 3 1/5, 3 11/20
We can make the common denominator 80 so:
3 63/80 stays the same, 3 1/5 both sides of the fraction are multiplied by 16 so it becomes 3 16/80, 3 11/20 both sides of the fraction are multiplied by 4 so it becomes 3 44/80
In ascending order the new fractions are:
3 16/80, 3 44/80, 3 63/80.
So in order from least to greatest, the fractions are:
3 1/5, 3 11/20, 3 63/80

Hope this helps :)
