Question 2 (ii)

Find:
$\frac{5}{63} - (\frac{- 6}{21})$

Open in App

Solution

$\frac{5}{63} - (\frac{- 6}{21}) = \frac{5 \times 1}{63 \times 1} - (\frac{- 6 \times 3}{21 \times 3}) = \frac{5}{63} - \frac{- 18}{63}$ [L.C.M of 63 and 21 is 63]
$= \frac{5 - (- 18)}{63} = \frac{5 + 18}{63} = \frac{23}{63}$
