please help evaluate this problem with the steps. m/n +m/2p, when m=-4/7,n=5/3,p=8/5

Answer 1

just plug in the numbers..

m/n +m/2p

= (-4/7) / (5/3) + (-4/7) / (16/5)
= (-4/7)(3/5) + (-4/7)(5/16)
= -12/35 + (-20/112)
= -12/35 - 5/28

now 35 = 5 x 7
and 28 = 4 x7
so the LCD = 5x4x7 = 140

carry on from here
