Question

Evaluate each of the following:

$\frac{5}{63} - \frac{- 8}{21}$

Open in App

Solution

To find: $\frac{5}{63} - \frac{- 8}{21}$

$∴ \frac{5}{63} - \frac{- 8}{21} = \frac{5}{63} - \frac{- 8 \times 3}{21 \times 3}$
$= \frac{5}{63} - \frac{- 24}{63}$
$= \frac{5 - (- 24)}{63}$
$= \frac{5 + 24}{63}$
$= \frac{29}{63}$

Thus, $\frac{5}{63} - \frac{- 8}{21} = \frac{29}{63}$

Evaluate each of the following: 563−−821

To find:563−−821 ∴563−−821=563−−8×321×3 =563−−2463 =5−(−24)63 =5+2463 =2963 Thus, 563−−821=2963

Evaluate each of the following:

$\frac{5}{63} - \frac{- 8}{21}$

To find: $\frac{5}{63} - \frac{- 8}{21}$

$∴ \frac{5}{63} - \frac{- 8}{21} = \frac{5}{63} - \frac{- 8 \times 3}{21 \times 3}$
$= \frac{5}{63} - \frac{- 24}{63}$
$= \frac{5 - (- 24)}{63}$
$= \frac{5 + 24}{63}$
$= \frac{29}{63}$

Thus, $\frac{5}{63} - \frac{- 8}{21} = \frac{29}{63}$
