30.3 is what percent of 225 - 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 225 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 225, so we can write it down as 100%=225.
4. We know, that x% equals 30.3 of the output value, so we can write it down as x%=30.3.
5. Now we have two simple equations:
1) 100%=225
2) x%=30.3
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%=225/30.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.3 is what percent of 225

100%/x%=225/30.3
(100/x)*x=(225/30.3)*x       - we multiply both sides of the equation by x
100=7.4257425742574*x       - we divide both sides of the equation by (7.4257425742574) to get x
100/7.4257425742574=x
13.466666666667=x
x=13.466666666667

now we have:
30.3 is 13.466666666667% of 225
