Question

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

Answer 1

$\huge \fbox \green{Answer:}$

$LHS = ( \frac{ - 9}{5} \times \frac{ - 10}{3} ) \times \frac{21}{ - 4}$

$= (\frac{ - 3}{1} \times \frac{ - 2}{1} ) \times \frac{21}{ - 4}$

$= 6 \times \frac{ - 21}{4} = \frac{ - 63}{2}$

$RHS = \frac{ - 9}{5} \times (\frac{ - 10}{3} \times \frac{21}{ - 4} )$

$= \frac{ - 9}{5} \times ( \frac{ - 5}{1} \times \frac{7}{ - 2} )$

$= \frac{ - 9}{5} \times \frac{35}{2} = \frac{ - 63}{2}$
