Answer:

C - 21:28

Step-by-step explanation:

this is solved by a little bit of trial and error. divide the possible answer numerators by 15, and check if it's the same for the denominator.

For C I did this:

Divided the denominators: 28 ÷ 20 = 1.4....so that's 1.4.

Let's test it out for the numerator now. 21 ÷ 15 = 1.4.

So there's your answer.
