Twenty fifths is 4 whole.
The answer is 8. One fifth of 20 is 4 because 20/5 is 4, and 4*2=8
1 = 5 fifths 2 = 10 fifths 3 = 15 fifths 4 = 20 fifths
5 fifths are in a whole (1). 75 fifths are in 15.
3/4 + 2/5 = 15/20 + 8/20 = 23/20
Four fifths times 5 is 20 fifths which is equal to 4.
I'm sure this is a trick question.One fifth of 20 is 4, five 4's are 20.So five fifths of 20 is 20.
