1780.8 is what percent of 42290 - 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 42290 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 100% equals 42290, so we can write it down as 100%=42290.
4. We know, that x% equals 1780.8 of the output value, so we can write it down as x%=1780.8.
5. Now we have two simple equations:
1) 100%=42290
2) x%=1780.8
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:
100%/x%=42290/1780.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1780.8 is what percent of 42290

100%/x%=42290/1780.8
(100/x)*x=(42290/1780.8)*x       - we multiply both sides of the equation by x
100=23.747753818509*x       - we divide both sides of the equation by (23.747753818509) to get x
100/23.747753818509=x
4.2109245684559=x
x=4.2109245684559

now we have:
