Question

10. Show that
(-3/8×5/9)×-4/13=-3/8×(5/9×-4/13​

Answer 1

Answer:

$(-\frac{3}{8} *\frac{5}{9})*-\frac{4}{13} = -\frac{3}{8}*(\frac{5}{9}*-\frac{4}{13})$

Step-by-step explanation:

The answer to $(-\frac{3}{8} *\frac{5}{9})*-\frac{4}{13}$:

1. $(-\frac{3}{8} *\frac{5}{9})*-\frac{4}{13}$
2. $-\frac{3}{8}*\frac{5}{9}=-\frac{15}{72}$
3. $-\frac{15}{72}*-\frac{4}{13}=\frac{60}{936}$
4. $-\frac{15}{72}*-\frac{4}{13}=\frac{60}{936}$

The answer to $-\frac{3}{8}*(\frac{5}{9}*-\frac{4}{13})$:

1. $-\frac{3}{8}*(\frac{5}{9}*-\frac{4}{13})$
2. $\frac{5}{9}*-\frac{4}{13}=-\frac{20}{117}$
3. $-\frac{3}{8}*-\frac{20}{117}=\frac{60}{936}$
4. $\frac{60}{936}$
