Answer 2

Answer:

181/140 = 1.29

Step-by-step explanation:

$\frac{2}{7} *\frac{3}{4} +\frac{4}{14} *(\frac{-3}{5} )+\frac{5}{4} \\\\\frac{6}{28} +\frac{4}{14} *(\frac{-3}{5} )+\frac{5}{4} \\\\\frac{6}{28} -\frac{12}{70} +\frac{5}{4} \\\\\frac{3}{14}- \frac{6}{35} +\frac{5}{4} \\\\Taking LCM,\\\\\frac{10(3)-4(6)+35(5)}{140} \\\\\frac{30-24+175}{140} \\\\\frac{205-24}{140} \\\\\frac{181}{140} \\\\1.29$
