What is 1270 percent of 3980 - 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 3980 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 3980 is 100%, so we can write it down as 3980=100%.
4. We know, that x is 1270% of the output value, so we can write it down as x=1270%.
5. Now we have two simple equations:
1) 3980=100%
2) x=1270%
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:
3980/x=100%/1270%
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 1270% of 3980

3980/x=100/1270
(3980/x)*x=(100/1270)*x       - we multiply both sides of the equation by x
3980=0.078740157480315*x       - we divide both sides of the equation by (0.078740157480315) to get x
3980/0.078740157480315=x
50546=x
x=50546

now we have:
1270% of 3980=50546
