Question

Verify : -7/3*(12/5*4/9)=(-7/3*12/5)*4/9

Answer 1

Answer:

$\\⟹\frac{ - 7}{3} ( \frac{12}{5} \times \frac{4}{9}) = ( \frac{ - 7}{3} \times \frac{12}{5} ) \times \frac{4}{9}$

$\\⟹\frac{ - 7}{3} ( \frac{48}{45} ) = ( \frac{ - 84}{15} ) \times \frac{4}{9}$

$\\⟹\frac{ - 336}{135} = \frac{ - 336}{135}$

hence,L.H.S.=R.H.S
