4 is what percent of 6.35 - 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 6.35 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 6.35, so we can write it down as 100%=6.35.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=6.35
2) x%=4
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%=6.35/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 6.35

100%/x%=6.35/4
(100/x)*x=(6.35/4)*x       - we multiply both sides of the equation by x
100=1.5875*x       - we divide both sides of the equation by (1.5875) to get x
100/1.5875=x
62.9921259843=x
x=62.9921259843

now we have:
4 is 62.9921259843% of 6.35
