Answer 1

Answer:

$\frac{9}{70}$

Step-by-step explanation:

$\frac{-1}{2}*\frac{3}{7}+\frac{4}{5}*\frac{3}{7}$

$=\frac{3}{7}[\frac{-1}{2}+\frac{4}{5}]\\\\= \frac{3}{7}[\frac{-5}{10}+\frac{8}{10}]\\\\=\frac{3}{7}[\frac{-5+8}{10}]\\\\=\frac{3}{7}[\frac{3}{10}]\\\\=\frac{3}{7}*\frac{3}{10}\\\\=\frac{9}{70}$

Answer 2

Answer:

-1/2 × 3/7 + 4/5 × 3/7

Answer is 0.128....

Step-by-step explanation:

-1/2 × 3/7 + 4/5 × 3/7

Using BODMAS rule:

= -3/14 + 12/35

= 5(-3) + 2(12) / 70

= -15 + 24/ 70

= 9/70

= 0.128....
