Question

what is 9/20 written as a percent

Answer 1

9/20=0.45
0.45×100=45
45/100 is the answer

Answer 2

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 $\frac{9}{20}$ as a percent, we need to find a fraction equivalent to $\frac{9}{20}$ that has a 100 in the denominator. We can do this by setting up a proportion.

$\frac{9}{20}$ = $\frac{n}{100}$

Now, we can use cross products to find the missing value.

20n = 900

÷20     ÷20   ← divide by 20 on both sides

n = 45

Therefore, $\frac{9}{20}$ is equal to $\frac{45}{100}$ or 45%.
