148.58 is what percent of 213 - 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 213 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 213, so we can write it down as 100%=213.
4. We know, that x% equals 148.58 of the output value, so we can write it down as x%=148.58.
5. Now we have two simple equations:
1) 100%=213
2) x%=148.58
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%=213/148.58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 148.58 is what percent of 213

100%/x%=213/148.58
(100/x)*x=(213/148.58)*x       - we multiply both sides of the equation by x
100=1.4335711401265*x       - we divide both sides of the equation by (1.4335711401265) to get x
100/1.4335711401265=x
69.755868544601=x
x=69.755868544601

now we have:
148.58 is 69.755868544601% of 213
