Question: Susie has 572 beans in the jar. One-fourth of them are red and one-third of the remaining beans are white. Then half of the remaining are green beans. How many green beans are there? Think carefully first, then make a decision:
Susie has 572 x 1 / 4 = 143 red beans. There were 572 - 143 = 429 beans that are not red. There are 429 x 1 / 3 = 143 white beans. So, there were 429 - 143 = 286 beans left. Therefore, 286 / 2 = 143 beans are green. So the answer is 143.
