4.8 is what percent of 189.21 - 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 189.21 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 189.21, so we can write it down as 100%=189.21.
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%=189.21
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%=189.21/4.8
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 189.21

100%/x%=189.21/4.8
(100/x)*x=(189.21/4.8)*x       - we multiply both sides of the equation by x
100=39.41875*x       - we divide both sides of the equation by (39.41875) to get x
100/39.41875=x
2.5368638021246=x
x=2.5368638021246

now we have:
4.8 is 2.5368638021246% of 189.21
