Question

Solve : $14a{b}^{2}c{d}^2÷7a^{2}b{c}^{2}d$

Answer 1

By dividing

$$\begin{gathered} 14a{b}^{2}c{d}^2÷7a^{2}b{c}^{2}d=\frac{14a{b}^{2}c{d}^2}{7a^{2}b{c}^{2}d} \\ =\frac{2\times 7\times a\times b\times b\times c\times d\times d}{7\times a\times a\times b\times c\times c\times d} \\ =\frac{2bd}{ac} \end{gathered}$$ (,$7,a,b,c$ and $d$ are common to both denominator and numerator, it's get cancelled.)

Hence, the above is required answer.
