8.42 is what percent of 9.02 - 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 9.02 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 9.02, so we can write it down as 100%=9.02.
4. We know, that x% equals 8.42 of the output value, so we can write it down as x%=8.42.
5. Now we have two simple equations:
1) 100%=9.02
2) x%=8.42
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%=9.02/8.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.42 is what percent of 9.02

100%/x%=9.02/8.42
(100/x)*x=(9.02/8.42)*x       - we multiply both sides of the equation by x
100=1.0712589073634*x       - we divide both sides of the equation by (1.0712589073634) to get x
100/1.0712589073634=x
93.348115299335=x
x=93.348115299335

now we have:
8.42 is 93.348115299335% of 9.02
