Question

A jar contains 360 beans. Of all the beans, 1/4 are white beans and the rest are black beans. What is the ration of white beans to black beans?

Answer 1

Answer is  1:3

Explanation:

1/4 = 0.25

0.25*360 = 90

90 white beans, 360-90 = 270 black beans

The ratio of white to black is 90:270 which fully simplifies to 1:3 after dividing both parts by the GCF 90.
