Question

find: -14/9/3/5*-4/7X15/16​

Answer 1

Answer:

Solution

\begin{gathered}( \frac{ - 14}{9} ) \times \frac{3}{5} \times (\frac{ - 4}{7} ) \times \frac{15}{16} \\ \end{gathered}(9−14)×53×(7−4)×1615

Remove all the brackets

\begin{gathered} = > \frac{-14}{9} \times \frac{3}{5} \times \frac{ - 4}{7} \times \frac{15}{16} \\ \end{gathered}=>9−14×53×7−4×1615

\begin{gathered} = > \frac{-14 \times 3}{9 \times 5} \times \frac{ - 4 \times 15}{7 \times 16} \\ \\ according \: to \: the \: property \: \\ whenever \: negative \: and \: positive \: \\ is \: being \: multiplied \: then \: the \: \\ answer \: comes \: in \: negative\end{gathered}=>9×5−14×3×7×16−4×15accordingtothepropertywhenevernegativeandpositiveisbeingmultipliedthentheanswercomesinnegative

\dfrac{\cancel{-42}}{\cancel{45}}45−42 \times\dfrac{\cancel{-60}}{\cancel{112}}112−60

= > \frac{14}{15} \times \frac{-15}{28}=>1514×28−15

\dfrac{\cancel{-14}}{\cancel{15}}15−14 X \dfrac{\cancel{-15}}{\cancel{28}}28−15

= > \frac{-1}{1} \times \frac{-1}{2}=>1−1×2−1

= > \frac{1}{2}=>21 answer
