13.33 is what percent of 19.7 - 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 19.7 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 19.7, so we can write it down as 100%=19.7.
4. We know, that x% equals 13.33 of the output value, so we can write it down as x%=13.33.
5. Now we have two simple equations:
1) 100%=19.7
2) x%=13.33
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%=19.7/13.33
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.33 is what percent of 19.7

100%/x%=19.7/13.33
(100/x)*x=(19.7/13.33)*x       - we multiply both sides of the equation by x
100=1.4778694673668*x       - we divide both sides of the equation by (1.4778694673668) to get x
100/1.4778694673668=x
67.664974619289=x
x=67.664974619289

now we have:
13.33 is 67.664974619289% of 19.7
