What is 420 percent of 487 - 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 487 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 487 is 100%, so we can write it down as 487=100%.
4. We know, that x is 420% of the output value, so we can write it down as x=420%.
5. Now we have two simple equations:
1) 487=100%
2) x=420%
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:
487/x=100%/420%
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 420% of 487

487/x=100/420
(487/x)*x=(100/420)*x       - we multiply both sides of the equation by x
487=0.23809523809524*x       - we divide both sides of the equation by (0.23809523809524) to get x
487/0.23809523809524=x
2045.4=x
x=2045.4

now we have:
420% of 487=2045.4
