Ling likes to listen to different types of music. One afternoon, she listened to 4 rap and 12 country songs. How can you describe the relationship between rap and country songs? Check all that apply.

Answer
A
For every 12 rap songs Ling listened to, she listened to 4 country songs.
B
For every rap song Ling listened to, she listened to 3 country songs.
C
Ling listened to 3 times as many country songs as rap songs.
D
Ling listened to a ratio of 4 rap songs to 12 country songs.

Explanation

Ling listened to 4 rap songs and 12 country songs. The ratio of country to rap is 12 ÷ 4 = 3, so she listened to 3 country songs for every rap song and 3 times as many country songs as rap songs. The ratio of rap to country is 4 to 12, so choice D is also correct. Choice A reverses the numbers.
