Open in App

Solution

To evaluate $50 \div (- 5)$ :
$50 \div (- 5)$ $= \frac{50}{(- 5)}$
By prime factorization method of $50 = 2 \times 5 \times 5$
By prime factorization method of $5 = 5 \times 1$
H.C.F of $50$ and $5$ $= 5$
Now, divide numerator and denominator by the H.C.F obtained, we get
$50 \div (- 5)$ $= \frac{50 \div 5}{(- 5) \div 5}$
$= \frac{10}{- 1}$
$= - 10$
Thus, $50 \div (- 5)$ $= - 10$ .
