40 is what percent of 1826 - 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 1826 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 1826, so we can write it down as 100%=1826.
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%=1826
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%=1826/40
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 1826

100%/x%=1826/40
(100/x)*x=(1826/40)*x       - we multiply both sides of the equation by x
100=45.65*x       - we divide both sides of the equation by (45.65) to get x
100/45.65=x
2.1905805038335=x
x=2.1905805038335

now we have:
40 is 2.1905805038335% of 1826
