To get operations easier lets get their denominators equal, that would be converting both to 16, lets start with that:
(3/4) = (4/4)<span>(3/4) = 4*3/*4*4 = 12/16
so, 3/4 = 12/16 they are equivalent, we can now perform the sum easily:
</span><span>3/4 + 1/16
= </span>12/16 <span>+ 1/16
= 13/16
that is the result in the lowest terms because we cannot reduce that fraction any more.</span>

Reorder -2y+7z-4
Hb=3.5, hd=2.25, hb+hd=7,
From the third, we can say hb=7-hd and we are told that:
3.5hb+2.25hd=19.5 using hb found above in this equation gives you:
3.5(7-hd)+2.25hd=19.5
24.5-3.5hd+2.25hd=19.5
-1.25hd=-5
hd=4
