What is 87.1 percent of 1122 - 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 1122 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 1122 is 100%, so we can write it down as 1122=100%.
4. We know, that x is 87.1% of the output value, so we can write it down as x=87.1%.
5. Now we have two simple equations:
1) 1122=100%
2) x=87.1%
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:
1122/x=100%/87.1%
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 87.1% of 1122

1122/x=100/87.1
(1122/x)*x=(100/87.1)*x       - we multiply both sides of the equation by x
1122=1.1481056257176*x       - we divide both sides of the equation by (1.1481056257176) to get x
1122/1.1481056257176=x
977.262=x
x=977.262

now we have:
87.1% of 1122=977.262
