90.2 is what percent of 219 - 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 219 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 219, so we can write it down as 100%=219.
4. We know, that x% equals 90.2 of the output value, so we can write it down as x%=90.2.
5. Now we have two simple equations:
1) 100%=219
2) x%=90.2
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%=219/90.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90.2 is what percent of 219

100%/x%=219/90.2
(100/x)*x=(219/90.2)*x       - we multiply both sides of the equation by x
100=2.4279379157428*x       - we divide both sides of the equation by (2.4279379157428) to get x
100/2.4279379157428=x
41.187214611872=x
x=41.187214611872

now we have:
90.2 is 41.187214611872% of 219
