Answer 1

Mari kita selesaikan setiap persamaan satu per satu.

1. \(\frac{4}{6} + \frac{2}{12}\)

, kita ubah pecahan ke bentuk paling sederhana:
\(\frac{4}{6} = \frac{2}{3}\)
\(\frac{2}{12} = \frac{1}{6}\)

Kemudian, kita cari KPK dari penyebutnya, yaitu 6:
\(\frac{2}{3} = \frac{4}{6}\)
\(\frac{1}{6} = \frac{1}{6}\)

Jadi, \(\frac{4}{6} + \frac{1}{6} = \frac{5}{6}\)

2. \(\frac{6}{12} + \frac{3}{3}\)

Ubah pecahan ke bentuk paling sederhana:
\(\frac{6}{12} = \frac{1}{2}\)
\(\frac{3}{3} = 1\)

Jadi, \(\frac{1}{2} + 1 = \frac{1}{2} + \frac{2}{2} = \frac{3}{2}\)

3. \(\frac{6}{8} - \frac{2}{7}\)

Cari KPK dari penyebutnya, yaitu 56:
\(\frac{6}{8} = \frac{42}{56}\)
\(\frac{2}{7} = \frac{16}{56}\)

Jadi, \(\frac{42}{56} - \frac{16}{56} = \frac{26}{56} = \frac{13}{28}\)

4. \(\frac{9}{18} - \frac{6}{3}\)

Ubah pecahan ke bentuk paling sederhana:
\(\frac{9}{18} = \frac{1}{2}\)
\(\frac{6}{3} = 2\)

Jadi, \(\frac{1}{2} - 2 = \frac{1}{2} - \frac{4}{2} = -\frac{3}{2}\)

5. \(\frac{12}{4} - \frac{6}{8}\)

Ubah pecahan ke bentuk paling sederhana:
\(\frac{12}{4} = 3\)
\(\frac{6}{8} = \frac{3}{4}\)

Jadi, \(3 - \frac{3}{4} = \frac{12}{4} - \frac{3}{4} = \frac{9}{4}\)

Jadi, jawabannya adalah:
1. \(\frac{5}{6}\)
2. \(\frac{3}{2}\)
3. \(\frac{13}{28}\)
4. \(-\frac{3}{2}\)
5. \(\frac{9}{4}\)
