MCQ
What should be subtracted from $\frac{-2}{3}$ to get$\frac{4}{5}?$
- A$\frac{22}{15}$
- ✓$\frac{-22}{15}$
- C$\frac{15}{22}$
- D$\frac{-15}{22}$
✓
Answer
Correct option: B.
$\frac{-22}{15}$
Difference of the given number and required number $=\frac{4}{5}$
Given number $=\frac{-2}{3}$
$\therefore$ Required number = Given number - Difference of the numbers
$=\frac{-2}{3}-\frac{4}{5}$
$=\frac{-2}{3}+\Big(\frac{-4}{5}\Big)$
$=\frac{-2\times5+(-4)\times3}{15}$
$=\frac{-10+(-12)}{15}$
$=\frac{-22}{15}$
Hence, the correct answer is option $(b).$
