3.45 is what percent of 7.4 - 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 7.4 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 7.4, so we can write it down as 100%=7.4.
4. We know, that x% equals 3.45 of the output value, so we can write it down as x%=3.45.
5. Now we have two simple equations:
1) 100%=7.4
2) x%=3.45
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%=7.4/3.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.45 is what percent of 7.4

100%/x%=7.4/3.45
(100/x)*x=(7.4/3.45)*x       - we multiply both sides of the equation by x
100=2.1449275362319*x       - we divide both sides of the equation by (2.1449275362319) to get x
100/2.1449275362319=x
46.621621621622=x
x=46.621621621622

now we have:
3.45 is 46.621621621622% of 7.4
