A new roll of wrapping paper has 6 5/8 yards of paper. Drew used 2 1/6 yards from the roll to wrap a gift. Which equation most closely estimates the number of yards of wrapping paper left on the roll?

First you have to make both fractions have the same denominator, so you can multiply each fraction by the others denominator.

5/8

To

(5*6) / (8*6)

And

1/6

To

(1*8) / (6*8)

Now it's 6 30/48 - 2 8/48

= 4 22/48

Now reduce to

= 4 11/24

So, 4 11/24 is the answer
