3.49 is what percent of 21.45 - 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 21.45 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 21.45, so we can write it down as 100%=21.45.
4. We know, that x% equals 3.49 of the output value, so we can write it down as x%=3.49.
5. Now we have two simple equations:
1) 100%=21.45
2) x%=3.49
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%=21.45/3.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.49 is what percent of 21.45

100%/x%=21.45/3.49
(100/x)*x=(21.45/3.49)*x       - we multiply both sides of the equation by x
100=6.1461318051576*x       - we divide both sides of the equation by (6.1461318051576) to get x
100/6.1461318051576=x
16.270396270396=x
x=16.270396270396

now we have:
3.49 is 16.270396270396% of 21.45
