19.65 is what percent of 418 - 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 418 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 418, so we can write it down as 100%=418.
4. We know, that x% equals 19.65 of the output value, so we can write it down as x%=19.65.
5. Now we have two simple equations:
1) 100%=418
2) x%=19.65
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%=418/19.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.65 is what percent of 418

100%/x%=418/19.65
(100/x)*x=(418/19.65)*x       - we multiply both sides of the equation by x
100=21.272264631043*x       - we divide both sides of the equation by (21.272264631043) to get x
100/21.272264631043=x
4.700956937799=x
x=4.700956937799

now we have:
19.65 is 4.700956937799% of 418
