Verify -2/5+[3/5+1/2]=[-2/5+3/5]+1/2​

Answer»

question:

VERIFY -2/5+[3/5+1/2]=[-2/5+3/5]+1/2

answer:

LHS =

\frac{ - 2}{5} + { \frac{3}{5} + \frac{1}{2} } = \frac{6 + 5}{10} + \frac{ - 2}{5} = \frac{11 - 4}{10} = \frac{7}{10}

RHS =

\frac{ - 2}{5} + \frac{3}{5} + \frac{1}{2} = \frac{ 1}{5} + \frac{1}{2} = \frac{5 + 2}{10} = \frac{7}{10}

hence LHS=RHS

hence PROVED .

hope it HELPS you ☺️
