Question

Привести следующие дроби к общему знаменателю быстро ​

Answer 1

$\quad \frac{6b^{2}}{2b}, \quad \frac{a^{2}}{2b};$

$\quad \frac{2a^{3}b}{2ab}, \quad \frac{c}{2ab};$

$\quad \frac{2b^{2}}{6ab}, \quad \frac{9ac}{6ab}, \quad \frac{6a^{2}b^{2}}{6ab};$

Объяснение:

$2) \quad 3b, \quad \frac{a^{2}}{2b}; \quad \frac{3b}{1}, \quad \frac{a^{2}}{2b}; \quad \frac{3b \cdot 2b}{1 \cdot 2b}, \quad \frac{a^{2}}{2b}; \quad \frac{6b^{2}}{2b}, \quad \frac{a^{2}}{2b};$

$3) \quad a^{2}, \quad \frac{c}{2ab}; \quad \frac{a^{2}}{1}, \quad \frac{c}{2ab}; \quad \frac{a^{2} \cdot 2ab}{1 \cdot 2ab}, \quad \frac{c}{2ab}; \quad \frac{2a^{3}b}{2ab}, \quad \frac{c}{2ab};$

$4) \quad \frac{b}{3a}, \quad \frac{3c}{2b}, \quad ab; \quad \frac{b \cdot 2b}{3a \cdot 2b}, \quad \frac{3c \cdot 3a}{2b \cdot 3a}, \quad \frac{ab \cdot 6ab}{1 \cdot 6ab}; \quad \frac{2b^{2}}{6ab}, \quad \frac{9ac}{6ab}, \quad \frac{6a^{2}b^{2}}{6ab};$
