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?

Two fifths.
two fifths is two parts of 5 or 2/5, first express that as part of 100 (as percents work that way) so 2/5 * 20/20 = 40 / 100. Thus two-fifths is 40 percent.
To find two-fifths of a number, you can multiply the number by 2/5 or divide the number by 5 and then multiply the result by 2.
7/20
To find out how many fifths are in two and two-fifths, we first need to convert the whole number, two, into fifths. Since one whole is equal to five fifths, two wholes would be equal to ten fifths. Adding the two-fifths gives us a total of twelve fifths in two and two-fifths.
four-fifths of 20 is 16.
two-fifths as a percent is 40% because 5 times 20=100 and 2 times 20= 40 and a percent is always over 100!
2/5 of 20 is 8.(2 / 5) * 20 = 8
