Question

13 out of 20 jelly beans
are green. What
percent of the jelly
beans are green?

Answer 1

Answer: 65% of the jellybeans are green

Explanation: Since there are 13 out of 20 green jellybeans, we can write the fraction 13/20 as a percent.

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. So to write 13/20 as a percent, we need to find a fraction that is equivalent to 13/20 that has a 100 in the denominator. We can do this by setting up a proportion.

`(13)/(20) = (n)/(100)`

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

1300 = 20n

÷20 ÷20

65 = n

Therefore, 65% of the jelly beans are green.
