42.79 is what percent of 356.64 - 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 356.64 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 356.64, so we can write it down as 100%=356.64.
4. We know, that x% equals 42.79 of the output value, so we can write it down as x%=42.79.
5. Now we have two simple equations:
1) 100%=356.64
2) x%=42.79
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%=356.64/42.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.79 is what percent of 356.64

100%/x%=356.64/42.79
(100/x)*x=(356.64/42.79)*x       - we multiply both sides of the equation by x
100=8.3346576302875*x       - we divide both sides of the equation by (8.3346576302875) to get x
100/8.3346576302875=x
11.998093315388=x
x=11.998093315388

now we have:
42.79 is 11.998093315388% of 356.64
