Saya mohon maaf kalo ada yg salah (emot hehe)

Penjelasan dengan langkah-langkah:

1.

[tex]2 \frac{1}{3} \times 2 = \frac{7}{2} \times 2 = \frac{14}{4} = 3 \frac{2}{4} [/tex]

2.

[tex]1 \frac{3}{5} - 0.2 = \frac{8}{5} - \frac{2}{10} = \frac{16}{10} - \frac{2}{10} = \frac{14}{10} = 1 \frac{4}{10} \div 2 = 1 \frac{2}{5} [/tex]

3.

[tex] \frac{4}{5} - 0.5 = \frac{4}{5} - \frac{5}{10} = \frac{8}{10} - \frac{5}{10} = \frac{3}{10} [/tex]

4.

[tex] \frac{1}{2} + \frac{7}{100} = \frac{50}{100} + \frac{7}{100} = \frac{57}{100} [/tex]
