0.78 is what percent of 3.59 - 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 3.59 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 3.59, so we can write it down as 100%=3.59.
4. We know, that x% equals 0.78 of the output value, so we can write it down as x%=0.78.
5. Now we have two simple equations:
1) 100%=3.59
2) x%=0.78
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%=3.59/0.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.78 is what percent of 3.59

100%/x%=3.59/0.78
(100/x)*x=(3.59/0.78)*x       - we multiply both sides of the equation by x
100=4.6025641025641*x       - we divide both sides of the equation by (4.6025641025641) to get x
100/4.6025641025641=x
21.727019498607=x
x=21.727019498607

now we have:
0.78 is 21.727019498607% of 3.59
