Question

What is the simplest form of 3/7+6/11+(-8/21)

Answer 1

Answer:

3/7+6/11+(-8/21) = 137/231.....

Answer 2

$\red{ Simplest \:form \:of \: \frac{3}{7} + \frac{6}{11} +</p><p>\frac{(-8)}{21}}$

$= \frac{3}{7} + \frac{6}{11}-</p><p>\frac{8}{21}$

$= \frac{3}{7} -</p><p>\frac{8}{21}+ \frac{6}{11}$

$= \frac{ 3\times 3 - 8}{21} + \frac{6}{11}$

$= \frac{ 9 -8}{21} + \frac{6}{11}$

$= \frac{ 1}{21} + \frac{6}{11}$

$= \frac{11+ 21\times 6 }{231}$

$= \frac{ 11 + 126}{231}$

$= \frac{ 137}{231}$

Therefore.,

$\red{ Simplest \:form \:of \: \frac{3}{7} + \frac{6}{11} +</p><p>\frac{(-8)}{21}}$

$\green {= \frac{ 137}{231} }$
