Jawaban:

1. ⅕ atau 0,2

2. 4 ⅕ atau 4,2

3. 7 ⅗ atau 7,6

Penjelasan dengan langkah-langkah:

$1. \: \frac{7}{10} - \frac{3}{6}$

$= \frac{7}{10} - \frac{1}{2}$

$= \frac{7}{10} - \frac{5 \times 1}{10}$

$= \frac{7 - 5}{10} = \frac{2}{10} = \frac{1}{5} = 0.2$

${}$

$2. \: 11 \frac{4}{10} - 7 \frac{3}{15}$

$= \frac{114}{10} - \frac{108}{15}$

$= \frac{342}{30} - \frac{216}{30} = \frac{126}{30}$

$= 4 \frac{6}{30} = 4 \frac{1}{5} = 4.2$

${}$

$3. \: 8 \frac{1}{5} - 0.6$

$8.2 - 0.6$

$7.6 = 7 \frac{6}{10} = 7 \frac{3}{5}$
