Question

verify that a+b=b+a by taking a=2/3 and b=3/7​

Answer 1

Answer :

Put a = ${\sf{\dfrac{2}{3}}}$ and b = ${\sf{\dfrac{3}{7}}}$ in the equation a + b = b + a

= ${\sf{\dfrac{2}{3}+ \dfrac{3}{7} = \dfrac{3}{7}+\dfrac{2}{3}}}$

= ${\sf{\dfrac{14+9}{21} = \dfrac{9+14}{21}}}$

= ${\sf{\dfrac{23}{21} = \dfrac{23}{21}}}$

Hence Proved !!!
