Elena's daughter sold 120 boxes of girlscout cookies. She was told that this amount represented 5% of the troops sale. How many boxes did the troop sell?

Answer 1

120/0.05 = ?

Answer 2

Let me put it another way. 5% = 1/20

120 is 1/20 of what number?

Multiply 120 by 20 to find the answer. Dividing by 0.05 is the same thing as multiplying by 20

Answer 3

part/whole = part/whole
120/X = 5/100
X=2400

troop sold 2400 cookies
