78.47 is what percent of 1600 - 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 1600 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 1600, so we can write it down as 100%=1600.
4. We know, that x% equals 78.47 of the output value, so we can write it down as x%=78.47.
5. Now we have two simple equations:
1) 100%=1600
2) x%=78.47
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%=1600/78.47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 78.47 is what percent of 1600

100%/x%=1600/78.47
(100/x)*x=(1600/78.47)*x       - we multiply both sides of the equation by x
100=20.389957945712*x       - we divide both sides of the equation by (20.389957945712) to get x
100/20.389957945712=x
4.904375=x
x=4.904375

now we have:
78.47 is 4.904375% of 1600
