Question

By what rational number should the sum of $\frac{18}{3}$ and $\frac{-7}{15}$ be divided to get $\frac{47}{6}$

Answer 1

$Sum=\frac{18}{3}-\frac{7}{15}=\frac{83}{15}$

let number be 'x'

$\frac{\frac{83}{15}}{x}=\frac{47}{6}\Rightarrow \frac{83\times 6}{15\times 47}=x$

$x=\frac{166}{235}$
