Answer 1

5 1/2 + 5 7/8 + 6 1/2 + 3 1/8 = ???

First take the two 1/2's and multiply the denominator and numerator by 4 because 4 times 2 = 8.

You will get two 4/8's

4/8 + 4/8= 8/8

8/8= 1 whole.
___________________________________________________________

Now take 7/8 + 1/8 = 8/8 that will turn into 1 whole too.

5+5+6+3= 19.

Now take your two added wholes( 2 wholes) and add.

2+19= 21

There is your answer is 21 pounds.
