13 9/14 Convert each mixed number intro an improper fraction, so 9 1/7 becomes 64/7. 4 1/2 becomes 9/2. Now, convert the 9/2 into a denominator with 7. To do this you need to multiple the numerator by 3.5. 3.5 x 9 = 31.5/7. Add those two improper fractions together to get 95.5/7. The numerator isn't whole, so multiply by 2 to get 191/14. now divide 191 by 14 and you get 13 whole times. 13 x 14 = 182. take the last leftover which is 191, subtract 182, and you get 9/14 left over. giving you 13 9/14.
