Question

Maya's school held an aluminum collection program in which they collected aluminum and brought it to be recycled. In the first week, Maya collected 4/20 lb of aluminum and her friend Abigail collected 7/8 lb. a. which girl collected more aluminum? b. how much aluminum did the two girls collect?

Answer 1

If you put this into the calculator, 4/20 is .2 and 7/8 is .875 therefore Abigail collected more. If you use them as the same denominator, you have 8/40 for Maya and 35/40. And if you add these two numbers together, you get 1.075 which is 43/40 as a fraction
