Question

bracket minus 2 upon 3 + 5 upon 7 bracket + - 1 upon 6 is equal to minus 2 upon 3 + bracket 5 upon 7 plus minus 1 upon 6 bracket​

Answer 1

Answer:

$(\frac{-2}{3}+\frac{5}{7})+(\frac{-1}{6})=(\frac{-2}{3})+(\frac{5}{7}+(\frac{-1}{6}))$

Step-by-step explanation:

To verify:

$(\frac{-2}{3}+\frac{5}{7})+(\frac{-1}{6})=(\frac{-2}{3})+(\frac{5}{7}+(\frac{-1}{6}))$

L.H.S

$=(\frac{-2}{3}+\frac{5}{7})+(\frac{-1}{6})$

$=(\frac{-14+15}{21})+(\frac{-1}{6})$

$=(\frac{1}{21})+(\frac{-1}{6})$

$=\frac{6-21}{126}$

$=\frac{-15}{126}$

$=\frac{-5}{42}$

R.H.S

$=(\frac{-2}{3})+(\frac{5}{7}+(\frac{-1}{6}))$

$=(\frac{-2}{3})+(\frac{30-7}{42})$

$=(\frac{-2}{3})+\frac{23}{42}$

$=\frac{-28+23}{42}$

$=\frac{-5}{42}$

L.H.S=R.H.S

Hence verified
