Question

verify-12/5+2/7=2/7+-12/5

Answer 1

$\frac{12}{5} + \frac{2}{7} = \frac{2}{7} + \frac{12}{5} \\ = \frac{84 + 10}{35} = \frac{10 + 84}{35} \\ = \frac{94}{35} = \frac{94}{35} \\ hence \: proved$

Answer 2

Thanks for your question !

Given equation -

12/5 + 2/7 = 2/7 + 12/5

Let we cross multiply, both RHS and LHS

84 + 10 / 35 = 10 + 84 / 35

94 / 35          =       94 / 35

LHS               =         RHS

   Hence, both the sides are equal and thus verified.
