Question
What number should be subtracted from $\frac{-2}{3}$ to get $\frac{-1}{6}$?
✓
Answer
Difference of two numbers $=\frac{-1}{6}$ One number $=\frac{-2}{3}$ $\therefore$ Second number $=\frac{2}{3}-\Big(\frac{-1}{6}\Big)$ $=\frac{-2}{3}+\frac{1}{6}$ $=\frac{-4+1}{6}$ $=\frac{-3}{6}$ $=\frac{-3\div3}{6\div3}$ $=\frac{-1}{2}$ $\therefore$ Second number $=\frac{-1}{2}$
