Question

Neil has 3 partially full cans of white paint. They contian 1/3 gallon, 1/5 gallon and 1/2 gallon of paint. About how much paint does neil have

Answer 1

1 1/30 gallon

Explanation:

Can A = 1/3 gallon

Can B = 1/5 gallon

Can C = 1/2 gallon

Total paint Neil has = Can A + Can B + Can C

= 1/3 + 1/5 + 1/2

The lowest common multiple of 3, 5 and 2 is 30

= (10+6+15) / 30

= 31/30

= 1 1/30 gallon of paint

Neil has a total of 1 1/30 gallon of paint
