Answer:
2 7/24C
Step-by-step explanation:
Start by finding the common denominator. In this case, it's 24. Next, start translation.
2/3C = 16/24C
7/8C = 21/24C
3/4C = 18/24C
Then find the sum.
16/24C + 21/24C + 18/24C = 55/24C = 2 7/24C
Answer:
-11/14
Step-by-step explanation: first you divide 33/4 and (-21/2), then reduce the numbers to -33/4 times 2/21 after you reduce both fractions multiply -11/2 times 1/7 and you get -11/14 your alternative form would br -0.785714
