Question

The product of two rational number is-3 by5 . If one number is 5 by 12 find the other number

Answer 1

Product of two Rational Number -: $\frac{-3}{5}$

One of the number -: $\frac{5}{12}$

Another number -:

$\frac{-3}{5} / \frac{5}{12}$

$\frac{-3}{5} *\frac{12}{5}$

$\frac{-36}{25}$

∴ Now we have to check if the other number is actually $\frac{-36}{25}$.

$\frac{5}{12} *\frac{-36}{25}$

$\frac{5/5}{12/12} *\frac{-36/12}{25/5}$

$\frac{1}{1}*\frac{-3}{5}$

$\frac{-3}{5}$

∴ The other number is $\frac{-3}{5}$.
