61 is what percent of 649 - 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 649 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 649, so we can write it down as 100%=649.
4. We know, that x% equals 61 of the output value, so we can write it down as x%=61.
5. Now we have two simple equations:
1) 100%=649
2) x%=61
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%=649/61
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 61 is what percent of 649

100%/x%=649/61
(100/x)*x=(649/61)*x       - we multiply both sides of the equation by x
100=10.639344262295*x       - we divide both sides of the equation by (10.639344262295) to get x
100/10.639344262295=x
9.3990755007704=x
x=9.3990755007704

now we have:
61 is 9.3990755007704% of 649
