What is 63.8 percent of 34 - 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 34 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 34 is 100%, so we can write it down as 34=100%.
4. We know, that x is 63.8% of the output value, so we can write it down as x=63.8%.
5. Now we have two simple equations:
1) 34=100%
2) x=63.8%
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:
34/x=100%/63.8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 63.8% of 34

34/x=100/63.8
(34/x)*x=(100/63.8)*x       - we multiply both sides of the equation by x
34=1.5673981191223*x       - we divide both sides of the equation by (1.5673981191223) to get x
34/1.5673981191223=x
21.692=x
x=21.692

now we have:
63.8% of 34=21.692
