4.74 is what percent of 31.57 - 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 31.57 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 31.57, so we can write it down as 100%=31.57.
4. We know, that x% equals 4.74 of the output value, so we can write it down as x%=4.74.
5. Now we have two simple equations:
1) 100%=31.57
2) x%=4.74
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%=31.57/4.74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.74 is what percent of 31.57

100%/x%=31.57/4.74
(100/x)*x=(31.57/4.74)*x       - we multiply both sides of the equation by x
100=6.6603375527426*x       - we divide both sides of the equation by (6.6603375527426) to get x
100/6.6603375527426=x
15.014254038644=x
x=15.014254038644

now we have:
4.74 is 15.014254038644% of 31.57
