Nomor 1.

$sf{frac{4}{7} + frac{2}{5}}$

$sf{= frac{20 + 14}{35}}$

$=sf{ bold{ frac{34}{35}}}$

$:$

Nomor 2.

$sf{frac{3}{8} + frac{2 }{16 }}$

$= sf{frac{6 + 2}{16}}$

$= sf{frac{8}{16}}$

(disederhanakan dengan dibagi 8)

$= sf{ frac{8div 8} {16div 8 }}$

$= sf{bold{ frac{1}{2}}}$

$:$

Nomor 3.

$sf{frac{1}{4} + frac{3}{6}}$

$= sf{frac{3 + 6}{12}}$

$= sf{frac{9}{12}}$

(disederhanakan dengan dibagi 3)

$= sf{frac{9div3}{12div3}}$

$= sf{bold{frac{3}{4}}}$

$:$

Nomor 4.

$sf{frac{3}{4} + frac{5}{8} }$

$=sf{ frac{6 + 5}{8}}$

$= sf{bold{frac{11}{8}}}$

$:$

Nomor 5.

$sf{frac{2}{5} + frac{2}{7}}$

$sf{= frac{14 + 10}{35}}$

$= sf{bold{frac{24}{35}}}$
