4.28 is what percent of 35 - 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 35 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 35, so we can write it down as 100%=35.
4. We know, that x% equals 4.28 of the output value, so we can write it down as x%=4.28.
5. Now we have two simple equations:
1) 100%=35
2) x%=4.28
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%=35/4.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.28 is what percent of 35

100%/x%=35/4.28
(100/x)*x=(35/4.28)*x       - we multiply both sides of the equation by x
100=8.1775700934579*x       - we divide both sides of the equation by (8.1775700934579) to get x
100/8.1775700934579=x
12.228571428571=x
x=12.228571428571

now we have:
4.28 is 12.228571428571% of 35
