303.7 is what percent of 345 - 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 345 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 345, so we can write it down as 100%=345.
4. We know, that x% equals 303.7 of the output value, so we can write it down as x%=303.7.
5. Now we have two simple equations:
1) 100%=345
2) x%=303.7
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%=345/303.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 303.7 is what percent of 345

100%/x%=345/303.7
(100/x)*x=(345/303.7)*x       - we multiply both sides of the equation by x
100=1.1359894632861*x       - we divide both sides of the equation by (1.1359894632861) to get x
100/1.1359894632861=x
88.028985507246=x
x=88.028985507246

now we have:
303.7 is 88.028985507246% of 345
