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?
Susie has 572 x 1/4 = 
<gadget id="calculator">572*1/4</gadget>
<output>143</output>
143 red beans.
There were 572 - 143 = 
<gadget id="calculator">572-143</gadget>
<output>429</output>
429 beans that are not red.
There are 429 x 1/3 = 
<gadget id="calculator">429*1/3</gadget>
<output>143</output>
143 white beans.
So, there were 429 - 143 = 
<gadget id="calculator">429-143</gadget>
<output>286</output>
286 beans left.
Therefore, 286/2 = 
<gadget id="calculator">286/2</gadget>
