What is 57.4 percent of 1220 - 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 1220 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 1220 is 100%, so we can write it down as 1220=100%.
4. We know, that x is 57.4% of the output value, so we can write it down as x=57.4%.
5. Now we have two simple equations:
1) 1220=100%
2) x=57.4%
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:
1220/x=100%/57.4%
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 57.4% of 1220

1220/x=100/57.4
(1220/x)*x=(100/57.4)*x       - we multiply both sides of the equation by x
1220=1.7421602787456*x       - we divide both sides of the equation by (1.7421602787456) to get x
1220/1.7421602787456=x
700.28=x
x=700.28

now we have:
57.4% of 1220=700.28
