70.4 is what percent of 84.8 - 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 84.8 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 84.8, so we can write it down as 100%=84.8.
4. We know, that x% equals 70.4 of the output value, so we can write it down as x%=70.4.
5. Now we have two simple equations:
1) 100%=84.8
2) x%=70.4
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%=84.8/70.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70.4 is what percent of 84.8

100%/x%=84.8/70.4
(100/x)*x=(84.8/70.4)*x       - we multiply both sides of the equation by x
100=1.2045454545455*x       - we divide both sides of the equation by (1.2045454545455) to get x
100/1.2045454545455=x
83.018867924528=x
x=83.018867924528

now we have:
70.4 is 83.018867924528% of 84.8
