What is 442 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 442% of the output value, so we can write it down as x=442%.
5. Now we have two simple equations:
1) 642=100%
2) x=442%
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%/442%
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 442% of 642

642/x=100/442
(642/x)*x=(100/442)*x       - we multiply both sides of the equation by x
642=0.2262443438914*x       - we divide both sides of the equation by (0.2262443438914) to get x
642/0.2262443438914=x
2837.64=x
x=2837.64

now we have:
442% of 642=2837.64
