3 per 7 + 2 per 3 =³ 4 per 5 + ² 1 per 5=

$sf : frac{3}{7} + frac{2}{3} =$

$sf : = frac{9}{21} + frac{14}{21}$

$sf : = frac{9 + 14}{21}$

$sf : = frac{23}{21}$

${ pmb{ underline{ boxed{ purple{ sf : = 1 frac{2}{21} }}}}}$

$sf : 3 frac{4}{5} + 2 frac{1}{5} =$

$sf : = (frac{5 times 3 + 4}{5} ) + ( frac{5 times 2 + 1}{5} )$

$sf : = frac{19}{5} + frac{11}{5}$

$sf : = frac{19 + 11}{5}$

$sf : = frac{30}{5}$

$sf : = 30 div 5$
