Tom and sami have two painting jobs but can only stop at the store once. the first job needs 1 4/5 gallons of paint. the second needs 12 1/3 gallons. how many gallon cans of paint should they buy?

Convert both to improper fractions

1 4/5 = (1*5 + 4)/5 = (5+4)/4 = 9/5

12 1/3 = (12*3 + 1)/3 = (36+1)/3 = 37/3

Find a common denominator - 15

9/5 = 27/15

37/3 = 185/15

Add them together

27/15 + 185/15 = 212/15

So 212/15 Gallons is needed.
