Question

The sum of two rational numbers is $\frac{-1}{2}$. If one of the numbers is $\frac{5}{6},$ find the other.

Answer 1

Sum of two numbers $=\frac{-1}{2}$ One number $=\frac{5}{6}$

$\therefore$ Second number $=\frac{-1}{2}-\left(\frac{5}{6}\right)$

$=\frac{-1}{2}-\frac{5}{6}$

$=\frac{-3-5}{6}=\frac{-8}{6}=\frac{-8÷2}{6÷2}=\frac{-4}{3}$
