The answer would be 13. Multiplying fractions is quite simple. All you have to do is multiply the numerators, then the denominators, and then simplify. 52 x 3 = 156, 3 x 4 = 12. The answer is now an improper fraction: 156/12, so you have to turn it into a mixed number. Since 12 goes into 156 evenly, the answer is 13. Hope this helps! :D
