What is 77 percent of 17400 - 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 17400 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 17400 is 100%, so we can write it down as 17400=100%.
4. We know, that x is 77% of the output value, so we can write it down as x=77%.
5. Now we have two simple equations:
1) 17400=100%
2) x=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:
17400/x=100%/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 77% of 17400

17400/x=100/77
(17400/x)*x=(100/77)*x       - we multiply both sides of the equation by x
17400=1.2987012987013*x       - we divide both sides of the equation by (1.2987012987013) to get x
17400/1.2987012987013=x
13398=x
x=13398

now we have:
77% of 17400=13398
