How much paint was used if 3/4 gallon was used for the living room, 5/7 gallon in the hallway and 1 gallon for the bedroom? ASAP

improper fraction: 69/28

Mixed number: 2 13/28

EXPLANATION

Just add the fractions. Find common denominators. We can multiply 5/7 by 4 and 3/4 by 7 to get common denominators

So

5/7 x 4 is 20/28

3/4 x 7 is 21/28

And 1 gallon is just 1/1 so we could also multiply by 28

1/1 x 28 = 28/28 (which also equals 1)

Now we can add

20/28 + 21/28 + 28/28 = 69/28

You can simplify to 2 13/28
