65% of the jellybeans are green

Step-by-step 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.

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.
