Question

What is 9/20 as a decimal and percent?

Answer 1

Answer: 45%

Step-by-step explanation: 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 will 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.

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

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

900 = 20n

÷20   ÷20   ← divide by 20 on both sides

  45 = n

Therefore, 9/20 is equal to 45 over 100 or 45%.
