What is 98.8 percent of 668 - 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 668 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 668 is 100%, so we can write it down as 668=100%.
4. We know, that x is 98.8% of the output value, so we can write it down as x=98.8%.
5. Now we have two simple equations:
1) 668=100%
2) x=98.8%
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:
668/x=100%/98.8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 98.8% of 668

668/x=100/98.8
(668/x)*x=(100/98.8)*x       - we multiply both sides of the equation by x
668=1.0121457489879*x       - we divide both sides of the equation by (1.0121457489879) to get x
668/1.0121457489879=x
659.984=x
x=659.984

now we have:
98.8% of 668=659.984
