Answer 1

Answer:

$\frac{27}{32}$

Step-by-step explanation:

$\boxed{\frac{\frac{5}{7} + \frac{1}{4} }{\frac{7}{8} }}$

First we should LCM of  7 and 4

$\bold{Multiples \:of \:7}=7, 14, 21, \red{28}, 35...$

$\bold{multiples \: of \: 4}=4,8,16,20,24,\red{28},32...$

LCM of 7 & 4 = 28

$\Rightarrow \frac{20\:+\:7}{28}$

$\Rightarrow \frac{27}{28}$

$\boxed{\frac{\frac{27}{28} }{\frac{7}{8} } }$

$= \frac{189}{224} =\frac{27}{32}$
