Question

verify (a+b)+C=a+(b+C), if. a=1/9,b=5/6,C=-7/9​

Answer 1

Answer:

$\left(\frac{1}{9}+\frac{5}{6}\right)+\left(-\frac{7}{9}\right)=\frac{1}{9}+\left(\frac{5}{6}+\left(-\frac{7}{9}\right)\right)\quad :\quad \mathrm{True}$

Step-by-step explanation:

$\left(\frac{1}{9}+\frac{5}{6}\right)+\left(-\frac{7}{9}\right)=\frac{1}{9}+\left(\frac{5}{6}+\left(-\frac{7}{9}\right)\right)$

$\frac{1}{6}=\frac{1}{6}$

$\mathrm{Both\:sides\:are\:equal}$

$\mathrm{True}$
