**Question 1: **Add

$\frac{8}{3}$ + $\frac{7}{4}$ ** Solution: **
Step 1:

Common denominator of 3 and 4 is 12

Step 2:

Make the denominator 12 of both the fractions

$\frac{8}{3}$ = $\frac{8 * 4}{3 * 4}$

= $\frac{32}{12}$

and $\frac{7}{4}$ = $\frac{7 * 3}{4 * 3}$

= $\frac{21}{12}$

Step 3:

$\frac{32}{12}$ + $\frac{21}{12}$ = $\frac{32 + 21}{12}$

= $\frac{53}{12}$

=> $\frac{8}{3}$ + $\frac{7}{4}$ = $\frac{53}{12}$
