Question

Z/12 = 4/5
what is z ?

Answer 1

Z equals 9.6! Hope it helps!

Answer 2

z/12 = 4/5
Multiply both sides by 12 to eliminate the fraction
(12)(z/12)=(4/5)(12)
On the left 12 cancels out
z=(12*4)/5
z= 48/5 =9 3/5= 9.6

Check:
Substitute the z=9.6 answer in original equation.
9.6/12 = 4/5
0.8=0.8

Hope this helps! :)
