74.2 is what percent of 300 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 300 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 300, so we can write it down as 100%=300.
4. We know, that x% equals 74.2 of the output value, so we can write it down as x%=74.2.
5. Now we have two simple equations:
1) 100%=300
2) x%=74.2
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%=300/74.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74.2 is what percent of 300

100%/x%=300/74.2
(100/x)*x=(300/74.2)*x       - we multiply both sides of the equation by x
100=4.0431266846361*x       - we divide both sides of the equation by (4.0431266846361) to get x
100/4.0431266846361=x
24.733333333333=x
x=24.733333333333

now we have:
74.2 is 24.733333333333% of 300
