4.3 is what percent of 8.4 - 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 8.4 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 8.4, so we can write it down as 100%=8.4.
4. We know, that x% equals 4.3 of the output value, so we can write it down as x%=4.3.
5. Now we have two simple equations:
1) 100%=8.4
2) x%=4.3
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%=8.4/4.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.3 is what percent of 8.4

100%/x%=8.4/4.3
(100/x)*x=(8.4/4.3)*x       - we multiply both sides of the equation by x
100=1.953488372093*x       - we divide both sides of the equation by (1.953488372093) to get x
100/1.953488372093=x
51.190476190476=x
x=51.190476190476

now we have:
4.3 is 51.190476190476% of 8.4
