49 is what percent of 324 - 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 324 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 324, so we can write it down as 100%=324.
4. We know, that x% equals 49 of the output value, so we can write it down as x%=49.
5. Now we have two simple equations:
1) 100%=324
2) x%=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%=324/49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49 is what percent of 324

100%/x%=324/49
(100/x)*x=(324/49)*x       - we multiply both sides of the equation by x
100=6.61224489796*x       - we divide both sides of the equation by (6.61224489796) to get x
100/6.61224489796=x
15.1234567901=x
x=15.1234567901

now we have:
49 is 15.1234567901% of 324
