To add these fractions, we first need to find a common denominator. In this case, the common denominator would be 8, since it is divisible by 12, 8, 1, and 4.
-7/12 + 1/8 - 5/1 + 3/4= (-72)/(122) + (13)/(83) + (-58)/(18) + (32)/(42)= -14/24 + 3/24 - 40/8 + 6/8= -14/24 + 3/24 - 40/8 + 6/8= (-14 + 3 - 40 + 6)/24= -45/24
Therefore, -7/12 + 1/8 - 5/1 + 3/4 = -45/24 which simplifies to -15/8.

-7/12 + 1/8 - 5/1 + 3/4
= (-72)/(122) + (13)/(83) + (-58)/(18) + (32)/(42)
= -14/24 + 3/24 - 40/8 + 6/8
= -14/24 + 3/24 - 40/8 + 6/8
= (-14 + 3 - 40 + 6)/24
= -45/24
Therefore, -7/12 + 1/8 - 5/1 + 3/4 = -45/24 which simplifies to -15/8.
