What is 96.3 percent of 642 - 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 642 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 642 is 100%, so we can write it down as 642=100%.
4. We know, that x is 96.3% of the output value, so we can write it down as x=96.3%.
5. Now we have two simple equations:
1) 642=100%
2) x=96.3%
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:
642/x=100%/96.3%
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 96.3% of 642

642/x=100/96.3
(642/x)*x=(100/96.3)*x       - we multiply both sides of the equation by x
642=1.0384215991693*x       - we divide both sides of the equation by (1.0384215991693) to get x
642/1.0384215991693=x
618.246=x
x=618.246

now we have:
96.3% of 642=618.246
