Question

{(-9)/5 × (-10)/3} × 21/-4 = (-9)/5 × {(-10)/3 × 21/-4}

Answer 1

Step-by-step explanation:

let take LHS

{(-9)/5 × (-10)/3} × 21/-4

{(-9)/5 × (-10)/3}

on solving this

{(-9)/5 × (-10)/3}=6

{(-9)/5 × (-10)/3} × 21/-4=6*(-21)/4=(-63)/2

let take RHS

(-9)/5 × {(-10)/3 × 21/-4}

{(-10)/3 × 21/-4}=35/2

(-9)/5 × {(-10)/3 × 21/-4}=(-9/5)*(35/2)

on solving this

(-9)/5 × {(-10)/3 × 21/-4}=(-63)/2

aso LHS=RHS

hence proved
