There are exactly 3 one-fifths in 9 20ths.
9 20ths is equal to 9/20, which is also equal to 0.45. 1/5 is equal to 0.2.
To find out how many one-fifths are in 9 20ths, we can divide 9/20 by 0.2. 9/20 / 0.2 = 4.5.
Since 4.5 cannot be represented as an integer, we round it up to 5. Therefore, there are exactly 3 one-fifths in 9 20ths.
