Question

2/5 × (-1/7) + 4/9× (-1/7) + 1/2
​

Answer 1

Answer:

219/630 = 0.34

Step-by-step explanation:

$\frac{2}{5}*( \frac{-1}{7})+ \frac{4}{9}*(\frac{-1}{7}) +\frac{1}{2} \\\\\frac{-2}{35} -\frac{4}{63} +\frac{1}{2} \\\\Taking LCM,\\\\\frac{28(-2)-10(4)+(315)1}{630} \\\\\frac{-56-40+315}{630} \\\\\frac{-96+315}{630} \\\\\frac{219}{630} \\\\0.34$
