Kevin has 3 3/4 pounds of pecans and 6 2/3 pounds of wulnuts. About how many more pounds of walnuts than pecans does Kevin have?

Answer 1

This is a simple subtracting problem that is a little more difficult because it’s fractions.

6 2/3 - 3 3/4

Now change to mixed numbers

20/3 - 15/4

Now make the denominators the same by multiplying each fraction by the opposite denominator.

4/4 x 20/3 - 3/3 x 15/4

80/12 - 45/12

35/12

Now change back to a mixed number.

2 11/12
