What is 87.05 percent of 800 - 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 800 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 800 is 100%, so we can write it down as 800=100%.
4. We know, that x is 87.05% of the output value, so we can write it down as x=87.05%.
5. Now we have two simple equations:
1) 800=100%
2) x=87.05%
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:
800/x=100%/87.05%
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 87.05% of 800

800/x=100/87.05
(800/x)*x=(100/87.05)*x       - we multiply both sides of the equation by x
800=1.1487650775416*x       - we divide both sides of the equation by (1.1487650775416) to get x
800/1.1487650775416=x
696.4=x
x=696.4

now we have:
87.05% of 800=696.4
