Question

5

a. A jar contains 550 beans. Of all the beans, 2/5 are white beans and the rest are navy beans. What is the ratio of white beans to navy beans?

Answer 1

fraction of navy beans = 1 - 2/5 = 3/5. So there are 2/5 * 550 = 220 white bean and 3/5 * 550 = 330 navy beans

ratio of white beans to navy beans is 220 : 330 = 2 : 3

Answer is 2:3.

Answer 2

2/5 of 550 = 220
that means 3/5 are navy beans.
550-220 = 330

white beans:navy beans
220:330

divide by 10=
22:33
divide by 11=
2:3
