Question

Simplify. 3/4−4z+5/4z−1/2+1/2z Enter your answer in the box.

Answer 1

3/4-4z+5/4z-1/2+1/2z
(simplify fractions by taking away)3/4-1/2=1/4
(simplify again but only fraction with a denominator of z)5/4z+1/2z=7/4z
so its 1/4+7/4z-4z

                                                           OR

I don't know if you're supposed to change by taking away 4z which is the same as 1/4z.
if so then
7/4z(previous calculation but you can use the beggining fractions if you want just add all 3 fractions with z as a denominator)-1/4z=6/4z
so its 1/4+6/4z

I don't know the others sorry
