Question

(-4/7×3/5) - (4/7×(-1)/5) +(2/5 +(-4/7)​

Answer 1

Step-by-step explanation:

(-4/7*3/5)-(4/7*(-1)/5+(2/5+(-4/7)

(-12/35)-(-4/35)+(-8/35)

(-12/35)+4/35-8/35

-20/35+4/35

-16/35

Answer 2

Answer:

-2/5 = -0.4

Step-by-step explanation:

$(\frac{-4}{7} *\frac{3}{5} )-(\frac{4}{7} *(\frac{-1}{5} ))+(\frac{2}{5}+(\frac{-4}{7} ) )\\\\\frac{-12}{35} -(\frac{-4}{35} )+(\frac{2}{5}-\frac{4}{7} )\\\\\frac{-12}{35} +\frac{4}{35} +(\frac{7(2)-5(4)}{35} )\\\\\frac{-12}{35} +\frac{4}{35} +(\frac{14-20}{35} )\\\\\frac{-12}{35} +\frac{4}{35} +(\frac{-6}{35} )\\\\\frac{-12}{35} +\frac{4}{35} -\frac{6}{35} \\\\\frac{-12+4-6}{35} \\\\\frac{-18+4}{35} \\\\\frac{-14}{35} \\\\\frac{-2}{5}$
