Jawaban:

1. 8/9

2. 4/5

3. 3/8

4. 19/20

Penjelasan dengan langkah-langkah:

Apabila penyebutnya belum sama maka disamakan dulu.
Apabila penyebutnya sudah sama bisa langsung dioperasikan ( dijumlahkan ).

$1. frac{7}{9} + frac{1}{9} = ...$

$frac{7}{9} + frac{1}{9} = frac{7 + 1}{9} = frac{8}{9}$

____________________________

$2. frac{1}{5} + frac{3}{5} = ...$

$frac{1}{5} + frac{3}{5} = frac{1 + 3}{5} = frac{4}{5}$

_____________________________

$3. frac{1}{4} + frac{1}{8} = ...$

$frac{1}{4} + frac{1}{8} = frac{1 times 2}{4 times 2} + frac{1 times 1}{8 times 1} = frac{2}{8} + frac{1}{8}$

$frac{2}{8} + frac{1}{8} = frac{3}{8}$

_____________________________

$4. frac{3}{4} + frac{1}{5} = ...$

$frac{3}{4} + frac{1}{5} = frac{3times 5}{4 times 5} + frac{1 times 4}{5 times 4} = frac{15}{20} + frac{4}{20}$

$frac{15}{20 } + frac{4}{20} = frac{15 + 4}{20} = frac{19}{20}$
