What is 1050 percent of 3870 - 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 3870 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 3870 is 100%, so we can write it down as 3870=100%.
4. We know, that x is 1050% of the output value, so we can write it down as x=1050%.
5. Now we have two simple equations:
1) 3870=100%
2) x=1050%
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:
3870/x=100%/1050%
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 1050% of 3870

3870/x=100/1050
(3870/x)*x=(100/1050)*x       - we multiply both sides of the equation by x
3870=0.095238095238095*x       - we divide both sides of the equation by (0.095238095238095) to get x
3870/0.095238095238095=x
40635=x
x=40635

now we have:
1050% of 3870=40635
