What is 64.2 percent of 1000 - 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 1000 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 1000 is 100%, so we can write it down as 1000=100%.
4. We know, that x is 64.2% of the output value, so we can write it down as x=64.2%.
5. Now we have two simple equations:
1) 1000=100%
2) x=64.2%
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:
1000/x=100%/64.2%
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 64.2% of 1000

1000/x=100/64.2
(1000/x)*x=(100/64.2)*x       - we multiply both sides of the equation by x
1000=1.5576323987539*x       - we divide both sides of the equation by (1.5576323987539) to get x
1000/1.5576323987539=x
642=x
x=642

now we have:
64.2% of 1000=642
