4.86 is what percent of 63.99 - 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 63.99 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 63.99, so we can write it down as 100%=63.99.
4. We know, that x% equals 4.86 of the output value, so we can write it down as x%=4.86.
5. Now we have two simple equations:
1) 100%=63.99
2) x%=4.86
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%=63.99/4.86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.86 is what percent of 63.99

100%/x%=63.99/4.86
(100/x)*x=(63.99/4.86)*x       - we multiply both sides of the equation by x
100=13.166666666667*x       - we divide both sides of the equation by (13.166666666667) to get x
100/13.166666666667=x
7.5949367088608=x
x=7.5949367088608

now we have:
4.86 is 7.5949367088608% of 63.99
