31 is what percent of 766 - 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 766 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 766, so we can write it down as 100%=766.
4. We know, that x% equals 31 of the output value, so we can write it down as x%=31.
5. Now we have two simple equations:
1) 100%=766
2) x%=31
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%=766/31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31 is what percent of 766

100%/x%=766/31
(100/x)*x=(766/31)*x       - we multiply both sides of the equation by x
100=24.709677419355*x       - we divide both sides of the equation by (24.709677419355) to get x
100/24.709677419355=x
4.0469973890339=x
x=4.0469973890339

now we have:
31 is 4.0469973890339% of 766
