What is 8.7 percent of 1558 - 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 1558 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 1558 is 100%, so we can write it down as 1558=100%.
4. We know, that x is 8.7% of the output value, so we can write it down as x=8.7%.
5. Now we have two simple equations:
1) 1558=100%
2) x=8.7%
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:
1558/x=100%/8.7%
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 8.7% of 1558

1558/x=100/8.7
(1558/x)*x=(100/8.7)*x       - we multiply both sides of the equation by x
1558=11.494252873563*x       - we divide both sides of the equation by (11.494252873563) to get x
1558/11.494252873563=x
135.546=x
x=135.546

now we have:
8.7% of 1558=135.546
