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.
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?
There are 20 fifths in 4 wholes. This can be calculated by multiplying the number of wholes (4) by the number of parts each whole is divided into (5). So, 4 wholes x 5 parts = 20 fifths. Each whole can be divided into 5 equal parts, and since there are 4 wholes, there are a total of 20 fifths.
