Jawaban:

4/5 + 2/8 = 32+10/40 = 42/40 => 21/20

Jawaban:

$frac{4}{5} + frac{2}{8}$

$= frac{4}{5} + frac{1 times 2}{4 times 2}$

$= frac{4}{5} + frac{1}{4}$

$= frac{4 times 4}{20} + frac{1 times 5}{20}$

$= frac{16}{20} + frac{5}{20}$

$= frac{(16 + 5)}{20}$

$= frac{21}{20}$

$= frac{1 times 20 + 1}{20}$

$= 1 frac{1}{20}$
