There are 75 one-fifths in the number 15. 15/(1/5) = 75 75 x (1/5) = 15
Starting with 1, it is 15.
15 and one half divided by 2 and one fifth = 7.5
x/15 = 6, x = 90, 10% = 9
One-tenth of 750 = 75 One-fifth of 75 = 15 One-third of 15 = 5 OR 750 x 1/10 x 1/5 x 1/3 = 750/150 = 5
One fifth is a rational fraction. It is not a whole number and cannot be made into one.
Two tenths equals one fifth..
-- To add one fifth to a number, add 0.2 to it. -- To find a new number that is one fifth bigger than the original number, multiply the original number by 1.2 .
