What is the solution to the proportion? 6/11 = m/121 A) 66 B) 11 C) 1/66 D) 1 11. What is the value of x, given PQ || BC? A) 10 B) 5 C) 7 D) 8

Question
Answer:
1. A  
7. C
8. C
10. A

1. Ratios are simplified by taking the least common multiple of both values and diving them until they are no longer divisible (in simplest form). 

7. The geometric mean can be found by taking the square root of A * B (the two values given, 6 and 13).

8. 189 ÷ 3 = 63

10. Cross multiplying the values across from each other, and dividing by the last value is the solution for finding the value of x in a proportion.
