Question

Find -4/5×3/7×15/16×(-14/9)​

Answer 1

$\huge\bold{Question:}$

$\frac{ - 4}{5} \times \frac{3}{7} \times \frac{15}{16} \times ( \frac{ - 14}{19} )$

$\huge\bold{\underline{Solution:}}$

1st method :-

$( - \frac{4 \times 3}{5 \times 7} ) \times ( \frac{15 \times ( - 14)}{16 \times 9} )$

$= \frac{ - 12}{35} \times ( \frac{ - 35}{24} ) = \frac{ - 12 \times ( - 35)}{35 \times 24} = \frac{1}{2}$

2nd method :-

$= ( \frac{ - 4}{5} \times \frac{ 15}{16} ) \times ( \frac{3}{7} \times ( \frac{ - 14}{9} ))$

We used commutative & associative property.

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

•°• Answer is $\frac{1}{2}$
