4.9 is what percent of 200 - 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 200 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 100% equals 200, so we can write it down as 100%=200.
4. We know, that x% equals 4.9 of the output value, so we can write it down as x%=4.9.
5. Now we have two simple equations:
1) 100%=200
2) x%=4.9
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:
100%/x%=200/4.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.9 is what percent of 200

100%/x%=200/4.9
(100/x)*x=(200/4.9)*x       - we multiply both sides of the equation by x
100=40.816326530612*x       - we divide both sides of the equation by (40.816326530612) to get x
100/40.816326530612=x
2.45=x
x=2.45

now we have:
4.9 is 2.45% of 200
