The box contains red and green balls. The ratio of the number of red balls to the number of green ones is 5: 8. What part of the number of green balls is red? How many times are there more green balls than red ones?

To solve this problem, remember, in order to find which part is the number A of the number B, you need to divide the number A by the number B. Let the red balls be 5x, and the green balls – 8x. Let’s calculate what part of the number of green balls are red.

5x / 8x = 5/8 part.

Let’s calculate how many times there are more green balls than red ones.

8/5 = 1.6 times.

Answer: 5/8 part, 1.6 times.
