Answer 1

$\displaystyle 5 + 1\frac{7}{10}=6\frac{7}{10}$

$\displaystyle \frac{3}{8}+3\frac{1}{8}=3\frac{4}{8}=3\frac{4*1}{4*2}=3\frac{1}{2}$

$\displaystyle 2\frac{5}{12}+5\frac{5}{12}=7\frac{10}{12}=7\frac{2*5}{2*6}=7\frac{5}{6}$

$\displaystyle 2\frac{4}{7}+3\frac{5}{7}=5\frac{9}{7}=6\frac{2}{7}$

$\displaystyle 3\frac{11}{16}+1\frac{13}{16}=4\frac{24}{16}=5\frac{8}{16}=5\frac{1*8}{2*8}=5\frac{1}{2}$
