What is 3.2 percent of 1580 - 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 1580 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 1580 is 100%, so we can write it down as 1580=100%.
4. We know, that x is 3.2% of the output value, so we can write it down as x=3.2%.
5. Now we have two simple equations:
1) 1580=100%
2) x=3.2%
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:
1580/x=100%/3.2%
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 3.2% of 1580

1580/x=100/3.2
(1580/x)*x=(100/3.2)*x       - we multiply both sides of the equation by x
1580=31.25*x       - we divide both sides of the equation by (31.25) to get x
1580/31.25=x
50.56=x
x=50.56

now we have:
3.2% of 1580=50.56
