40 is what percent of 1696 - 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 1696 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 1696, so we can write it down as 100%=1696.
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%=1696
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%=1696/40
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 1696

100%/x%=1696/40
(100/x)*x=(1696/40)*x       - we multiply both sides of the equation by x
100=42.4*x       - we divide both sides of the equation by (42.4) to get x
100/42.4=x
2.3584905660377=x
x=2.3584905660377

now we have:
40 is 2.3584905660377% of 1696
