Question

5 2/3 + 7 1/2 + 8 3/4 =

Answer 1

Answer:

21 11/12

Step-by-step explanation:

5 2/3 + 7 1/2 + 8 3/4 =

The common denominator is 12

5 2/3 = 5 2/3*4/4 = 5 8/12

7 1/2 * 6/6 = 7 6/12

8 3/4 * 3/3 = 8 9/12

I like to line them up vertically

5   8/12

7   6/12

8   9/12

--------------

20  23/12

But the last is an improper fraction

12 goes into 23 1 time   23-12 =11

with 11 left over

20 + 1 11/12

21 11/12
