4.17 is what percent of 278 - 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 278 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 278, so we can write it down as 100%=278.
4. We know, that x% equals 4.17 of the output value, so we can write it down as x%=4.17.
5. Now we have two simple equations:
1) 100%=278
2) x%=4.17
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%=278/4.17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.17 is what percent of 278

100%/x%=278/4.17
(100/x)*x=(278/4.17)*x       - we multiply both sides of the equation by x
100=66.666666666667*x       - we divide both sides of the equation by (66.666666666667) to get x
100/66.666666666667=x
1.5=x
x=1.5

now we have:
4.17 is 1.5% of 278
