7.21 is what percent of 297 - 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 297 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 297, so we can write it down as 100%=297.
4. We know, that x% equals 7.21 of the output value, so we can write it down as x%=7.21.
5. Now we have two simple equations:
1) 100%=297
2) x%=7.21
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%=297/7.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.21 is what percent of 297

100%/x%=297/7.21
(100/x)*x=(297/7.21)*x       - we multiply both sides of the equation by x
100=41.19278779473*x       - we divide both sides of the equation by (41.19278779473) to get x
100/41.19278779473=x
2.4276094276094=x
x=2.4276094276094

now we have:
7.21 is 2.4276094276094% of 297
