Twenty fifths is 4 whole.
1 = 5 fifths 2 = 10 fifths 3 = 15 fifths 4 = 20 fifths
The answer is 8. One fifth of 20 is 4 because 20/5 is 4, and 4*2=8
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.
Oh, dude, it's like super easy. To find two fifths of 20, you just divide 20 by 5 (because fifths, you know) to get 4. Then you multiply that by 2, which gives you 8. So, two fifths of 20 is 8. Math is fun, right?
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.
