30 is what percent of 2223 - 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 2223 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 2223, so we can write it down as 100%=2223.
4. We know, that x% equals 30 of the output value, so we can write it down as x%=30.
5. Now we have two simple equations:
1) 100%=2223
2) x%=30
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%=2223/30
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30 is what percent of 2223

100%/x%=2223/30
(100/x)*x=(2223/30)*x       - we multiply both sides of the equation by x
100=74.1*x       - we divide both sides of the equation by (74.1) to get x
100/74.1=x
1.3495276653171=x
x=1.3495276653171

now we have:
30 is 1.3495276653171% of 2223
