What is 12.77 percent of 1988 - 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 1988 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 1988 is 100%, so we can write it down as 1988=100%.
4. We know, that x is 12.77% of the output value, so we can write it down as x=12.77%.
5. Now we have two simple equations:
1) 1988=100%
2) x=12.77%
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:
1988/x=100%/12.77%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 12.77% of 1988

1988/x=100/12.77
(1988/x)*x=(100/12.77)*x       - we multiply both sides of the equation by x
1988=7.8308535630384*x       - we divide both sides of the equation by (7.8308535630384) to get x
1988/7.8308535630384=x
253.8676=x
x=253.8676

now we have:
12.77% of 1988=253.8676
