49 is what percent of 634 - 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 634 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 634, so we can write it down as 100%=634.
4. We know, that x% equals 49 of the output value, so we can write it down as x%=49.
5. Now we have two simple equations:
1) 100%=634
2) x%=49
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%=634/49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49 is what percent of 634

100%/x%=634/49
(100/x)*x=(634/49)*x       - we multiply both sides of the equation by x
100=12.938775510204*x       - we divide both sides of the equation by (12.938775510204) to get x
100/12.938775510204=x
7.7287066246057=x
x=7.7287066246057

now we have:
49 is 7.7287066246057% of 634
