5.29 is what percent of 6.4 - 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 6.4 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 6.4, so we can write it down as 100%=6.4.
4. We know, that x% equals 5.29 of the output value, so we can write it down as x%=5.29.
5. Now we have two simple equations:
1) 100%=6.4
2) x%=5.29
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%=6.4/5.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.29 is what percent of 6.4

100%/x%=6.4/5.29
(100/x)*x=(6.4/5.29)*x       - we multiply both sides of the equation by x
100=1.2098298676749*x       - we divide both sides of the equation by (1.2098298676749) to get x
100/1.2098298676749=x
82.65625=x
x=82.65625

now we have:
5.29 is 82.65625% of 6.4
