320.34 is what percent of 424 - 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 424 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 424, so we can write it down as 100%=424.
4. We know, that x% equals 320.34 of the output value, so we can write it down as x%=320.34.
5. Now we have two simple equations:
1) 100%=424
2) x%=320.34
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%=424/320.34
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 320.34 is what percent of 424

100%/x%=424/320.34
(100/x)*x=(424/320.34)*x       - we multiply both sides of the equation by x
100=1.3235936817132*x       - we divide both sides of the equation by (1.3235936817132) to get x
100/1.3235936817132=x
75.551886792453=x
x=75.551886792453

now we have:
320.34 is 75.551886792453% of 424
