649.99 is what percent of 928 - 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 928 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 928, so we can write it down as 100%=928.
4. We know, that x% equals 649.99 of the output value, so we can write it down as x%=649.99.
5. Now we have two simple equations:
1) 100%=928
2) x%=649.99
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%=928/649.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 649.99 is what percent of 928

100%/x%=928/649.99
(100/x)*x=(928/649.99)*x       - we multiply both sides of the equation by x
100=1.4277142725273*x       - we divide both sides of the equation by (1.4277142725273) to get x
100/1.4277142725273=x
70.042025862069=x
x=70.042025862069

now we have:
649.99 is 70.042025862069% of 928
