Question

There are 16 tennis balls and 20 golf balls in a box.

What is the ratio of tennis balls to all the balls in the box?

Answer 1

4:9

Explanation:

16 tennis balls + 20 golf balls = 36 balls in the box in total

16 tennis balls to 36 balls

16:36 = 4:9

Answer 2

Since both 16 and 20 are divisible by 4, 16:20 is reduced to 4:5. The final answer is 4:5.
