Shyla’s research shows that 8 empty cans make 1/4 pound of aluminum. Shyla wants to know how many cans it takes to make 5 pounds of aluminum. How many cans are there per pound of aluminum
To find out how many cans it takes to make 5 pounds of aluminum, Shyla can use a proportion.
8 cans = 1/4 pound
x cans = 5 pounds
x = (5 pounds * 8 cans)/(1/4 pound)
Simplifying the expression:
x = 40 cans
So, it takes 40 cans to make 5 pounds of aluminum.
To find out how many cans there are per pound of aluminum, Shyla can use the reciprocal of the previous ratio:
1 pound = 8/40 cans
1 pound = 0.2 cans
Therefore, there are 0.2 cans per pound of aluminum.
