7.4 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 7.4 of the output value, so we can write it down as x%=7.4.
5. Now we have two simple equations:
1) 100%=324
2) x%=7.4
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%=324/7.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.4 is what percent of 324

100%/x%=324/7.4
(100/x)*x=(324/7.4)*x       - we multiply both sides of the equation by x
100=43.783783783784*x       - we divide both sides of the equation by (43.783783783784) to get x
100/43.783783783784=x
2.283950617284=x
x=2.283950617284

now we have:
7.4 is 2.283950617284% of 324
