3.7 is what percent of 12.3 - 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 12.3 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 12.3, so we can write it down as 100%=12.3.
4. We know, that x% equals 3.7 of the output value, so we can write it down as x%=3.7.
5. Now we have two simple equations:
1) 100%=12.3
2) x%=3.7
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%=12.3/3.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.7 is what percent of 12.3

100%/x%=12.3/3.7
(100/x)*x=(12.3/3.7)*x       - we multiply both sides of the equation by x
100=3.3243243243243*x       - we divide both sides of the equation by (3.3243243243243) to get x
100/3.3243243243243=x
30.081300813008=x
x=30.081300813008

now we have:
3.7 is 30.081300813008% of 12.3
