Solution

To evaluate: $(- 30) \div 10$
$(- 30) \div 10$ $= \frac{- 30}{10}$
By prime factorization method of $30 = 2 \times 5 \times 3$
By prime factorization method of $10 = 2 \times 5$
H.C.F of $30$ and $10$ $= 2 \times 5 = 10$
Now, divide numerator and denominator by the H.C.F obtained, we get
$(- 30) \div 10$ $= \frac{- 30 \div 10}{10 \div 10}$
$= \frac{- 3}{1}$
Thus, $(- 30) \div 10$ $= - 3$
