75 is what percent of 316 - 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 316 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 316, so we can write it down as 100%=316.
4. We know, that x% equals 75 of the output value, so we can write it down as x%=75.
5. Now we have two simple equations:
1) 100%=316
2) x%=75
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%=316/75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 75 is what percent of 316

100%/x%=316/75
(100/x)*x=(316/75)*x       - we multiply both sides of the equation by x
100=4.21333333333*x       - we divide both sides of the equation by (4.21333333333) to get x
100/4.21333333333=x
23.7341772152=x
x=23.7341772152

now we have:
75 is 23.7341772152% of 316
