Question

write the multiplicative inverse of $\frac{3}{7}$

Answer 1

Finding multiplicative inverse of $\frac{3}{7}$:

when any two integer $a$ and $b$are multiplied where if $a$ and $b$are integers then its multiplicative inverse is given by

$\Rightarrow a\times b=1$

such that , $b$ is reciprocal of $a$

Here ,let us assume that $a=\frac{3}{7}$

$\Rightarrow \frac{3}{7}\times b=1$

$\Rightarrow b=\frac{7}{3}$

Therefore, the multiplicative inverse of $\frac{3}{7}$ is $\frac{7}{3}$.
