30 is what percent of 2574 - 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 2574 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 2574, so we can write it down as 100%=2574.
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%=2574
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%=2574/30
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 2574

100%/x%=2574/30
(100/x)*x=(2574/30)*x       - we multiply both sides of the equation by x
100=85.8*x       - we divide both sides of the equation by (85.8) to get x
100/85.8=x
1.1655011655012=x
x=1.1655011655012

now we have:
30 is 1.1655011655012% of 2574
