7.91 is what percent of 245.42 - 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 245.42 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 245.42, so we can write it down as 100%=245.42.
4. We know, that x% equals 7.91 of the output value, so we can write it down as x%=7.91.
5. Now we have two simple equations:
1) 100%=245.42
2) x%=7.91
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%=245.42/7.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.91 is what percent of 245.42

100%/x%=245.42/7.91
(100/x)*x=(245.42/7.91)*x       - we multiply both sides of the equation by x
100=31.026548672566*x       - we divide both sides of the equation by (31.026548672566) to get x
100/31.026548672566=x
3.2230462065031=x
x=3.2230462065031

now we have:
7.91 is 3.2230462065031% of 245.42
