Question

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?

Answer 1

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.
