7.74 is what percent of 430 - 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 430 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 430, so we can write it down as 100%=430.
4. We know, that x% equals 7.74 of the output value, so we can write it down as x%=7.74.
5. Now we have two simple equations:
1) 100%=430
2) x%=7.74
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%=430/7.74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.74 is what percent of 430

100%/x%=430/7.74
(100/x)*x=(430/7.74)*x       - we multiply both sides of the equation by x
100=55.555555555556*x       - we divide both sides of the equation by (55.555555555556) to get x
100/55.555555555556=x
1.8=x
x=1.8

now we have:
7.74 is 1.8% of 430
