8
40

?


8%

20%

25%

40%

Answer 1

Answer: 20%

Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.

So to write 8/40 as a percent, we need to find a fraction equivalent to 8/40 with a 100 in the denominator. We can do this by setting up a proportion.

So we have $\frac{8}{40} = \frac{n}{100}$.

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

800 = 40n

÷40    ÷40   ← divide both sides of the equation by 40

  20 = n

So, 8/40 is equal to 20/100 or 20%.
