МатематикаВопрос:
42. \(\frac{3}{12}\) : \(\frac{3}{4}\)
Ответ:
1. Simplify first fraction: $$\frac{3}{12} = \frac{1}{4}$$.
2. Divide: $$\frac{1}{4} : \frac{3}{4} = \frac{1}{4} \cdot \frac{4}{3} = \frac{1}{3}$$.
2. Divide: $$\frac{1}{4} : \frac{3}{4} = \frac{1}{4} \cdot \frac{4}{3} = \frac{1}{3}$$.
