ok -5/3(8) + 3/8(3) = -40/24 + 9/24 = -31/24 = 1 -7/24

OpenStudy (callisto):
-5/3+ 3/8
= ( -5/3)(8/8) +( 3/8 )(3/3)
= -40/24 + 9/24
= -31/24
for addition of fraction, the demoninator should be the same, sp find the LCM of them, that is 24. as you multiply something at the bottom, you need to multiply the same number at the top of the fraction so that its value doesn't change.
ps: ( -5/3)(8/8) = (-5/3)x1 = -5/3
and ( 3/8 )(3/3) =(3/8)x1 = 3/8
