Which pair of fractions shows \( \frac{7}{9} \) and \( \frac{5}{12} \) correctly converted with their least common denominator?

A. \( \frac{28}{36} \) and \( \frac{15}{36} \)
B. \( \frac{34}{36} \) and \( \frac{29}{36} \)
C. \( \frac{56}{72} \) and \( \frac{30}{72} \)
D. \( \frac{84}{108} \) and \( \frac{45}{108} \)

the common denominator number is (i mean at least)** 36. **so when we multiply 7/9 with 4/4 . NOW we have 28/36. ****for the other multiply 5/12 with 3/3 now we have 15/36. the answer is A . hope it helps :) :)
