Let's solve the equation for Y by first rewriting it as: 100% / 40 = 50% / Y
Drop the percentage marks to simplify your calculations: 100 / 40 = 50 / Y
Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 40 ) = 50
To isolate Y, multiply both sides by 40 / 100, we will have: Y = 50 ( 40 / 100 )
Computing the right side, we get: Y = 20
This leaves us with our final answer: 50% of 40 is 20
