## anonymous 4 years ago Thom began building a chair last week. He 5/16 built of the chair during the weekdays, and 7/16 on the weekend. Which of the following can be used to find how much of the chair

1. anonymous

Write 16+16 to get 32/12 . Simplify to 8/3 . ------ 5+7 Write 5+7+16 to get 28/16 . Simplify to 1 3/4 . ------- 16 Write 5+7 to get 12/16 . Simplify to 3/4 . ---- 16 Write 5+7 to get 12/32 . Simplify to 3/8 . ---- 16+16

So far, he has built $\frac{5}{16} + \frac{7}{16}$ of the chair. So how do you add that fraction?

6. anonymous

3/4
