For which value of m is start fraction 4 over 16 end fraction equals start fraction m over 24 end fraction a proportion?

A. m = 6
B. m = 8
C. m = 12
D. m = 14

We can cross-multiply to see if the fractions are proportional:

4/16 = m/24

Multiplying both sides by 24:

(4/16) * 24 = m

Simplifying:

6 = m

Therefore, the answer is A. m = 6.
