49 is what percent of 651 - 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 651 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 651, so we can write it down as 100%=651.
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%=651
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%=651/49
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 651

100%/x%=651/49
(100/x)*x=(651/49)*x       - we multiply both sides of the equation by x
100=13.285714285714*x       - we divide both sides of the equation by (13.285714285714) to get x
100/13.285714285714=x
7.5268817204301=x
x=7.5268817204301

now we have:
49 is 7.5268817204301% of 651
