Can someone tell me what 2/3=z/15 your a life

First, do 15 * 2/3. You get 10 as your outcome. Then, you make that ten the numerator with 15 as your denominator. When you put that into your calculator, you get 2/3 as your outcome. Which means that 10 is the correct answer! I hope this helps!

2/3 = z/15   (Move z/15 to the other side)
2/3 - z/15 = 0 (find the common denominator which is 3)  
6/15- 3z/45 = 3z/30 = 10
