Can somebody please help explain what I'm supposed to do?
"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?"
In part 'a', you are supposed to compare the amount of aluminium that both girls collected, and identify which one collected more. To do this, you have to figure out whether 4/20 or 7/8 is bigger, for which you must multiply them to give a common denominator.
In part 'b', you are supposed to find the total aluminium collected by adding up the given amounts of aluminium, for which, again, you must have a common denominator.
Ah, thank you for clarifying! :D
