Question

Using appropriate property of rational numbers find [7/11+(5/7+3/22)]​

Answer 1

Answer:

$\frac{7}{11} +(\frac{5}{7} +\frac{3}{22})$

First we will do $\frac{5}{7} +\frac{3}{22}$ cause it is in brackets so we need to do it first

lcm=154

$\frac{5}{7} =\frac{110}{154} \\\\\frac{3}{22} =\frac{15}{154}$

so, $\frac{110}{154} +\frac{15}{154} = \frac{125}{154}$

now,$\frac{125}{154} +\frac{3}{11}$

lcm=154

$\frac{3}{11}=\frac{42}{154} \\\\and \frac{42}{154} will$remain the same

so now,$\frac{42}{154} +\frac{125}{154} =\frac{169}{154}$

happy 2 help :)

pls mark me as the brainliest
