7.4 is what percent of 23.4 - 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 23.4 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 23.4, so we can write it down as 100%=23.4.
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%=23.4
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%=23.4/7.4
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 23.4

100%/x%=23.4/7.4
(100/x)*x=(23.4/7.4)*x       - we multiply both sides of the equation by x
100=3.1621621621622*x       - we divide both sides of the equation by (3.1621621621622) to get x
100/3.1621621621622=x
31.623931623932=x
x=31.623931623932

now we have:
7.4 is 31.623931623932% of 23.4
