Answer
Given: $\frac{3}{4}+\frac{7}{16}+\frac{5}{8}$
$=\frac{3\times4}{4\times4}+\frac{7\times1}{16\times1}+\frac{5\times2}{8\times2}$
$($because $LCM$ of $4, 16$ and $8$ is $16)$
$=\frac{12}{16}+\frac{7}{16}+\frac{10}{16}$
$=\frac{12+7+10}{16}$
$=\frac{29}{16}$
$=\frac{3\times4}{4\times4}+\frac{7\times1}{16\times1}+\frac{5\times2}{8\times2}$
$($because $LCM$ of $4, 16$ and $8$ is $16)$
$=\frac{12}{16}+\frac{7}{16}+\frac{10}{16}$
$=\frac{12+7+10}{16}$
$=\frac{29}{16}$
