What is 220 percent of 2100 - 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 2100 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 2100 is 100%, so we can write it down as 2100=100%.
4. We know, that x is 220% of the output value, so we can write it down as x=220%.
5. Now we have two simple equations:
1) 2100=100%
2) x=220%
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:
2100/x=100%/220%
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 220% of 2100

2100/x=100/220
(2100/x)*x=(100/220)*x       - we multiply both sides of the equation by x
2100=0.45454545454545*x       - we divide both sides of the equation by (0.45454545454545) to get x
2100/0.45454545454545=x
4620=x
x=4620

now we have:
220% of 2100=4620
