An interior designer purchased 4 1/2 yards, 6 2/3 yards and 9 1/4 yards of fabric to make curtains How many yards of fabric did they purchase?

Simply add up all.

4 1/2 + 6 2/3 + 9 1/4

(4 + 6 + 9) + 1/2 + 2/3 + 1/4

19 6/12 + 8/12 + 3/12 = (6+8+3) / 12 = 17/12

19 17/12

19 1 5/12

19 + 1 5/12

= 20 5/12

20 5/12 yards was purchased.

I'm trying to find out the answer
