4.47 is what percent of 6.39 - 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 6.39 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 6.39, so we can write it down as 100%=6.39.
4. We know, that x% equals 4.47 of the output value, so we can write it down as x%=4.47.
5. Now we have two simple equations:
1) 100%=6.39
2) x%=4.47
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%=6.39/4.47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.47 is what percent of 6.39

100%/x%=6.39/4.47
(100/x)*x=(6.39/4.47)*x       - we multiply both sides of the equation by x
100=1.4295302013423*x       - we divide both sides of the equation by (1.4295302013423) to get x
100/1.4295302013423=x
69.953051643192=x
x=69.953051643192

now we have:
4.47 is 69.953051643192% of 6.39
