D. 6 7/8
Step-by-step explanation:
First, convert 2 3/4 to an improper fraction.
2 times 4 = 8
8+3=11
11/4 ÷2/5
Then, flip the second fraction and change the sign to multiplication.
11/4 × 5/2
Multiply.
11 × 5 = 55
4 × 2 = 6
55/6
Simplify the fraction.
6 7/8
You have to add 3+3+5.
It equals 11.
Then divide 132 by 11.
It equals 12.
Then you have to put it into the ratio, so you multiply each number by 12.
So the ratio is 36:36:60
