Question

A jar contains 900 beans. Of all the beans, 7/10 are white beans and the rest are azuki beans. What is the ratio of white beans to azuki beans?

Answer 1

Given that in the jar, navy beans and white beans in a ratio of 1:9. Let the amount of navy beans be x.

Then, the amount of white beans in the jar is 9x.

Given that amount of navy beans is x=90

Total amount of beans in the jar is x+9x=10x=10+90=900

So the ratio is 1:9
