GHLMNNN62 $\frac{8}{12} - \frac{9}{14} = {?}$

Pertama, samakan penyebut pecahan menggunakan KPK. ↓

$\frac{8 \times 14}{12 \times 14} - \frac{9 \times 12}{14 \times 12} = \frac{112}{168} - \frac{108}{168} = {?}$

Kedua, kerjakan seperti biasa. ↓

$\frac{112 - 108}{168} = \frac{4}{168} = \frac{1}{42}$

Semoga membantu;b
