Answer 2

First find common denominators.

their common denominator is 12. Remember that what you multiply to the denominator, you must multiply the same to the numerator

2/3(4/4) = 8/12

1/2(6/6) = 6/12

7/4(3/3) = 21/12

Remember to bring the signs.

8/12 + 6/12 - 21/12

Simplify.

(8/12 + 6/12) - 21/12

14/12 - 21/12

-7/12
