you mean 20 divided by 3 1/5
3 1/5=16/5
when you want to divide you multiply bythe reciprocal
so 20/(16/5)=20*5/16=100/16
=25/4 or 6 1/4

First, convert the 3 1/5 to an improper fraction (denominator multiplied by the number in front plus the numerator--i.e., 3 * 5 + 1 = 16), so 20 / 16/5. Multiply the numerator and denominator by 5/16, so:
20 * 5/16 = 100/16
--------------
16/5 * 5/16 = 1
Because the denominator is 1, it isn't important (anything over 1 is anything), so your answer is 100/16 = 25/4 = 6 1/4
