Let G represent Green beans , W → White beans , and B →Black Beans .
• G : W : B
4 : 3 : 5
• (we can see that the green beans are in multiplicity of 8 ( 4*8 =32 ounces, therefore the ration of other beans is to be multiplied by 8 as well. )
4*8=32 : 3*8= 24 : 5*8= 40
0. This means that Jack used ,40 ounces of black beans .
,1. Total ounce of the salad will then be : 32 +24 +40 = 96 ounce.
