Question

: (-4/5) × (3/14) × (15/16) × (-21/9)​

Answer 1

Given:

(-4/5) × (3/14) × (15/16) × (-21/9)​

$=\frac{-4}{5}* \frac{3}{14} *\frac{15}{16} *\frac{-21}{9}$

$=-0.8*\frac{3}{14} *\frac{15}{16}* \frac{-21}{9}$

$=-0.8*0.214*\frac{15}{16} *\frac{-21}{9}$

$=-0.8*0.241*0.937*\frac{-21}{9}$

=-0.8×0.241×0.937×-2.333

=0.42

Hence the answer is 0.42

Answer 2

• As per given data in the question, we have to find the multiplication of the given fractions.
• Given data- $-\frac{4}{5}\times\frac{3}{14}\times\frac{15}{16}\times \frac{-21}{9}.$
• Step 1- when we multiply negative number to negative number the result will be positive.

• Solution:-

         $=-\frac{4}{5}\times\frac{3}{14}\times\frac{15}{16}\times \frac{-21}{9}.$

         $=\frac{3}{8}$

        The multiplication of $-\frac{4}{5}\times\frac{3}{14}\times\frac{15}{16}\times \frac{-21}{9}.$ will be $\frac{3}{8}$ .
