Question

Melanie went to the hardware store and bought 2 1/2 gallons of white paint and 1 1/4 gallons of black paint. How many gallons of paint did Melanie buy altogether?

A student solved the problem this way:


2 1/2 + 1 1/4 = 2 2/4 + 1 1/4 = 3 3/4


Melanie bought 3 3/4 gallons of paint.

Use a similar strategy to solve this problem.

Juan bought 1 1/9 gallons of black paint, 2 1/3 gallons of white paint, and a 3/4 inch paint brush.

How many gallons of paint did Juan buy altogether?


A.
3 2/9 gallons

B.
3 1/3 gallons

C.
3 4/9 gallons

D.
3 2/3 gallons

Answer 1

1 1/9 + 2 1/3
change the 1/3 to 9th's so we have
1 1/9 + 2 3/9 = 3 4/9

C
