What is 55 percent of 1400 - 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 1400 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 1400 is 100%, so we can write it down as 1400=100%.
4. We know, that x is 55% of the output value, so we can write it down as x=55%.
5. Now we have two simple equations:
1) 1400=100%
2) x=55%
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:
1400/x=100%/55%
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 55% of 1400

1400/x=100/55
(1400/x)*x=(100/55)*x       - we multiply both sides of the equation by x
1400=1.8181818181818*x       - we divide both sides of the equation by (1.8181818181818) to get x
1400/1.8181818181818=x
770=x
x=770

now we have:
55% of 1400=770
