7.4 is what percent of 34.6 - 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 34.6 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 34.6, so we can write it down as 100%=34.6.
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%=34.6
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%=34.6/7.4
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 34.6

100%/x%=34.6/7.4
(100/x)*x=(34.6/7.4)*x       - we multiply both sides of the equation by x
100=4.6756756756757*x       - we divide both sides of the equation by (4.6756756756757) to get x
100/4.6756756756757=x
21.387283236994=x
x=21.387283236994

now we have:
7.4 is 21.387283236994% of 34.6
