-3/5 +8/35=?
First get a common denominator; in this case it's 35.
-21/35 + 8/35 = -13/35
Try the others yourself. We'll be glad to check your answers.
7/9-(-13/18)
14/18-(-13/18)
27/18=3/2
is this correct?
(4)(-3/2)
(8/2)(-3/2)= -24/4
-6
Right! (4)(-3/2) = -6
Right. And 3/2 = 1 1/2
ok I have -21-(-9)=-12
wouldn't -21-(-21)=0
