Answer:
D
Step-by-step explanation:
x -91
1. 25% if 1/4, so we want to find 1/4 of 176. Best way to get the result is just divide 176 by 4, so 176:4=44 - its the answer.
2. To get the answer we can use proportion
100% -----------20
90% ---------- x
crossmultiply now
100x=90*20
100x=1800 /:100 divide both sides by 100
x=18 - its the answer
3. Similar problem
24 ---------- x
30 ---------- 100%
crossmultiply now
24*100%=30x
2400%=30x /:30 divide both sides by 30
2400%:30=x
80%=x - its the answer
Step-by-step explanation:
We can create a ratio and solve.

We then isolate for x and get 9
