Answer 2

2$\frac{1}{3}$ = $\frac{2*3+1}{3}$ = $\frac{7}{3}$

7$\frac{2}{3}$ = $\frac{7*3 + 2}{3}$ = $\frac{23}{3}$

8$\frac{5}{9}$ = $\frac{8*9 + 5}{9}$ = $\frac{77}{9}$

10$\frac{3}{13}$ = $\frac{10*13+3}{13}$ = $\frac{133}{13}$

4$\frac{11}{12}$ = $\frac{4*12+11}{12}$ = $\frac{59}{12}$

15$\frac{12}{13}$ = $\frac{15*13+12}{13}$
