Can someone please check if my brother got this correct?

Question

My younger brother needed help with this Math question:

The ratio of employees to computers in a certain company is 11 to 6. If there are 121 employees in the company, how many computers are there?

(A) 65

(B) 660

(C) 61

(D) 66

He got (C) 61, is he correct?

Answer 1

Hello, (C) is not the correct answer. The correct answer is (D).

11/6 = 121/X

1) Cross multiply: 11*X = 121*6

2) 11*X = 726

3) Divide both sides by 11: (11*X)/11 = 726/11

4) X = 726/11 = 66

66 is correct answer (D).
