40 is what percent of 682 - 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 682 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 682, so we can write it down as 100%=682.
4. We know, that x% equals 40 of the output value, so we can write it down as x%=40.
5. Now we have two simple equations:
1) 100%=682
2) x%=40
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%=682/40
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40 is what percent of 682

100%/x%=682/40
(100/x)*x=(682/40)*x       - we multiply both sides of the equation by x
100=17.05*x       - we divide both sides of the equation by (17.05) to get x
100/17.05=x
5.8651026392962=x
x=5.8651026392962

now we have:
40 is 5.8651026392962% of 682
