Question

Zane makes a mixture for his chainsaw. He uses a 3:2 ratio for cups of gasoline to cups of solvent. if Zane uses 2 gallons of gasoline to make the mixture, how much solvent does he need

Answer 1

2 is 2/3 of 3. So 3 times 2/3 is 3. And 3 is a ratio to 2(cups of solvent). Using that logic we can find 2/3 of the cups of solvent. 2 times 2/3 is 4/3. Thus, he would need 4/3 cups of solvent.
