15 CD players in 8 hours
x CD players in 37 hours

For each sentence above, divide the values in the order from left to right to form these fractions: 15/8 and x/37

Now equate the two fractions and cross multiply to isolate x

15%2F8+=+x%2F37

15%2A37+=+8%2Ax cross multiply

555+=+8x

8x+=+555

8x%2F8+=+555%2F8 Divide both sides by 8

x+=+555%2F8

x+=+69.375

Rounding to the nearest integer, the answer is 69.
