Question

7. Simplify: 3-7/6-11/12

Answer 1

3-7/6-11/12

Find the common denominator which is 12

Pretend that there is a 1 for 3.

Multiply by 12 for 3/1

3(12)/ 1(12)=36/12

Multiply by 2 for 7/6

7(2)/6(2)= 14/12

36/12-14/12-11/12

22/12-11/12

=11/12

Answer: 11/12

Answer 2

11/12

Explanation:

we have:

3-7/6-11/12

3-7/6 = (18-7)/6 = 11/6

so we have:

11/6-11/12 = (132-66)/72

(132-66)/72= 66/72

finally we have:

66/72 = 11/12
