<h3><u>Answer :</u><u>-</u><u> </u></h3>

<h3><u>Question :- </u></h3>

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

<h2><u>Solution :- </u></h2>

<h3><u>First </u><u>way:</u></h3>

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

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

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

<h3><u>Second way : </u></h3>

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

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

[ ↑ Using commutativity and Associativity ] ...

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

A different number can be placed in each box to make the number sentences

goblinko [34]

I’m not sure but one of the numbers could be 1 and the other could be 0.5. These are possible answers that could go in the boxes. I got this because I knew that I had to get a number that’s less than 10. So when you do 8+1 you get 9 which is less than 10. I picked 0.5 because it said in the question we can’t pick the same number so I picked a decimal. When you do 8+0.5 you get 8.5 which is less than 10.
Hope this helped
