4.9 is what percent of 18.21 - 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 18.21 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 18.21, so we can write it down as 100%=18.21.
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%=18.21
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%=18.21/4.9
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 18.21

100%/x%=18.21/4.9
(100/x)*x=(18.21/4.9)*x       - we multiply both sides of the equation by x
100=3.7163265306122*x       - we divide both sides of the equation by (3.7163265306122) to get x
100/3.7163265306122=x
26.908292147172=x
x=26.908292147172

now we have:
4.9 is 26.908292147172% of 18.21
