Answer:33.33
1. We assume, that the number 150 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 150, so we can write it down as 100%=150.
4. We know, that x% equals 50 of the output value, so we can write it down as x%=50.
5. Now we have two simple equations:
1) 100%=150
2) x%=50
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=150/50
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 50 is what percent of 150
100%/x%=150/50
(100/x)*x=(150/50)*x - we multiply both sides of the equation by x
100=3*x - we divide both sides of the equation by (3) to get x
100/3=x
33.3333333333=x
x=33.3333333333
(the 3 repeats after the decimal point)
hope this helped :D
