4 is what percent of 7.58 - 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 7.58 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 7.58, so we can write it down as 100%=7.58.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=7.58
2) x%=4
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%=7.58/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 7.58

100%/x%=7.58/4
(100/x)*x=(7.58/4)*x       - we multiply both sides of the equation by x
100=1.895*x       - we divide both sides of the equation by (1.895) to get x
100/1.895=x
52.770448548813=x
x=52.770448548813

now we have:
4 is 52.770448548813% of 7.58
