398.89 is what percent of 710 - 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 710 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 710, so we can write it down as 100%=710.
4. We know, that x% equals 398.89 of the output value, so we can write it down as x%=398.89.
5. Now we have two simple equations:
1) 100%=710
2) x%=398.89
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%=710/398.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 398.89 is what percent of 710

100%/x%=710/398.89
(100/x)*x=(710/398.89)*x       - we multiply both sides of the equation by x
100=1.7799393316453*x       - we divide both sides of the equation by (1.7799393316453) to get x
100/1.7799393316453=x
56.181690140845=x
x=56.181690140845

now we have:
398.89 is 56.181690140845% of 710
