51 is what percent of 1636 - 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 1636 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 1636, so we can write it down as 100%=1636.
4. We know, that x% equals 51 of the output value, so we can write it down as x%=51.
5. Now we have two simple equations:
1) 100%=1636
2) x%=51
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%=1636/51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51 is what percent of 1636

100%/x%=1636/51
(100/x)*x=(1636/51)*x       - we multiply both sides of the equation by x
100=32.078431372549*x       - we divide both sides of the equation by (32.078431372549) to get x
100/32.078431372549=x
3.1173594132029=x
x=3.1173594132029

now we have:
51 is 3.1173594132029% of 1636
