What is 22.2 percent of 210 - 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 210 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 210 is 100%, so we can write it down as 210=100%.
4. We know, that x is 22.2% of the output value, so we can write it down as x=22.2%.
5. Now we have two simple equations:
1) 210=100%
2) x=22.2%
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:
210/x=100%/22.2%
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 22.2% of 210

210/x=100/22.2
(210/x)*x=(100/22.2)*x       - we multiply both sides of the equation by x
210=4.5045045045045*x       - we divide both sides of the equation by (4.5045045045045) to get x
210/4.5045045045045=x
46.62=x
x=46.62

now we have:
22.2% of 210=46.62
