Cara Menentukan Pecahan senilai

2. Pembilang dan penyebut dikali bilangan yang sama
misalnya : $\frac{6}{12}=\frac{6\times2}{12\times2}=\frac{12}{24}$ sehingga

: $\frac{6}{12}senilai\ dengan\frac{12}{24}\ atau\ \frac{6}{12}=\frac{6}{12}$

3. Pembilang dan penyebut dibagi dengan bilangan yang sama
misalnya:

\frac{6}{12}=\frac{6\ :\ 2}{12\ :\ 2}=\frac{3}{6}

,

\frac{6}{12}=\frac{6\ :\ 3}{12\ :\ 3}=\frac{2}{4}

sehingga

\frac{6}{12}senilai\ dengan\ \frac{3}{6}senilai\ dengan\ \frac{2}{4}

atau

\frac{6}{12}=\frac{3}{6}=\frac{2}{4}
