Question

A store sold 2 CDs for every 6 DVDs. If 564 DVDs were sold, how many CDs were sold?

(A) 188 CDS
(B) 287 CDS
(C) 282 CDS
(D) 141 CDS

Answer 1

I took the test and got A) 188 CDS correct

Answer 2

2CD = 6DVD

so, 1CD = 3DVD, 1DVD = 1/3 CD (just consider for equation)

564 DVD = 564/3 CD =188CD
