Question

find using appropriate properties​

Answer 1

Step-by-step explanation:

Your question :

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

Your answer:

$\frac{ - 12}{35} \times \frac{15}{16} \times ( - \frac{14}{19} )$

[ multiply the first two rational numbers ]

$= \frac{ - 3}{7} \times \frac{3}{4} \times ( - \frac{14}{19} )$

[ now cancel the numbers ]

$= \frac{ 9}{28} \times \frac{14}{19}$

[ negative sign is removed because "-" * "-" = +]

$= \frac{9}{4} \times \frac{2}{19}$

[ canceling the numbers ]

$</u></strong><strong><u>=</u></strong><strong><u>\frac{9}{2} \times \frac{1}{19}$

Now, your final answer is 9/38
