What is 49.5 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 49.5% of the output value, so we can write it down as x=49.5%.
5. Now we have two simple equations:
1) 210=100%
2) x=49.5%
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%/49.5%
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 49.5% of 210

210/x=100/49.5
(210/x)*x=(100/49.5)*x       - we multiply both sides of the equation by x
210=2.020202020202*x       - we divide both sides of the equation by (2.020202020202) to get x
210/2.020202020202=x
103.95=x
x=103.95

now we have:
49.5% of 210=103.95
