To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write
(9)/(20) as a percent, we need to find a fraction equivalent to
(9)/(20) that has a 100 in the denominator. We can do this by setting up a proportion.


(9)/(20) =
(n)/(100)

20n = 900

÷20 ÷20

n = 45

Therefore,
(9)/(20) is equal to 45%.

To write
(9)/(20) as a decimal, we need to find a fraction equivalent to
(9)/(20) with a 100 in the denominator. Notice that if we multiply the numerator and the denominator of
(9)/(20) by 5, we get the equivalent fraction
(45)/(100) which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point. So we can write
(45)/(100) as 0.45.

Therefore,
(9)/(20) is equivalent to 0.45.
