4.8 is what percent of 8.51 - 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 8.51 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 8.51, so we can write it down as 100%=8.51.
4. We know, that x% equals 4.8 of the output value, so we can write it down as x%=4.8.
5. Now we have two simple equations:
1) 100%=8.51
2) x%=4.8
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:
100%/x%=8.51/4.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.8 is what percent of 8.51

100%/x%=8.51/4.8
(100/x)*x=(8.51/4.8)*x       - we multiply both sides of the equation by x
100=1.7729166666667*x       - we divide both sides of the equation by (1.7729166666667) to get x
100/1.7729166666667=x
56.404230317274=x
x=56.404230317274

now we have:
4.8 is 56.404230317274% of 8.51
