Question

Find the sum:
$\frac{19}{9}+2\frac{5}{8}$

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

$\frac{19}{9}+2\frac{5}{8}\Rightarrow \frac{19}{9}+\frac{21}{8}$ $(2\frac{5}{8}=2\times 8+5=\frac{21}{8})$
Since 8 and 9 have no common factor, LCM = $8\times 9$
= 72
$\frac{{19}^{x^8}}{9}+\frac{{21}^{x^9}}{8}=\frac{152+189}{72}$
=$\frac{341}{72}$
=$4\frac{53}{72}$
