Answer 2

$\frac{5}{6}$  +  $\frac{3}{8}$ =  $\frac{40 + 18}{48}$ =  $\frac{58}{48}$

$\frac{5}{8}$  +  $\frac{3}{4}$ =   $\frac{20 + 24}{32}$ =  $\frac{42}{32}$

$\frac{12}{25}$  +  $\frac{13}{30} =$ $\frac{360 + 325}{750} = \frac{685}{750}$

$\frac{8}{9} + \frac{3}{7} = \frac{56 + 27}{21} = \frac{83}{21}$

$\frac{5}{6} - \frac{1}{2} = \frac{10 - 6 }{12} = \frac{4}{12}$

$\frac{17}{12} - \frac{3}{4} = \frac{68 - 36}{48} = \frac{32}{48}$

$\frac{9}{10} - \frac{2}{5} = \frac{45 - 20}{50} = \frac{25}{52}$
