hope this helped
When you are dividing fractions you just flip the second fraction upside down and multiply the two fractions
So the first is
½ x 6/1 = 6/2 = 3
For the second you write them as improper fractions then do the same
So it is
3/2 / 1/8 = 3/2 x 8/1 = 24/2 = 12
So the answer to the first question is 3 and the second is 12
Remove parentheses
2c - 4 + 5c + 11
Combine like terms
Answer: 7c + 7
Yes you are right. it's 132
