z = 50
Step-by-step explanation:
The equation 27/90=15/z can be written as the following if we simplify a little:
3/10=15/z.
remember 27=3*9 and 90=9*10, hence 27/90=3/10
Now lets multiply both sides by variable 'z'.
we have 3/10 * z = 15/z * z
3/10 z=15
Now lets multiply by 10/3
3/10 * z * 10/3 = 15*10/3
z = 50
