306.5 is what percent of 351 - 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 351 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 351, so we can write it down as 100%=351.
4. We know, that x% equals 306.5 of the output value, so we can write it down as x%=306.5.
5. Now we have two simple equations:
1) 100%=351
2) x%=306.5
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%=351/306.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 306.5 is what percent of 351

100%/x%=351/306.5
(100/x)*x=(351/306.5)*x       - we multiply both sides of the equation by x
100=1.1451876019576*x       - we divide both sides of the equation by (1.1451876019576) to get x
100/1.1451876019576=x
87.321937321937=x
x=87.321937321937

now we have:
306.5 is 87.321937321937% of 351
