311.43 is what 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 100% equals 1400, so we can write it down as 100%=1400.
4. We know, that x% equals 311.43 of the output value, so we can write it down as x%=311.43.
5. Now we have two simple equations:
1) 100%=1400
2) x%=311.43
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%=1400/311.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 311.43 is what percent of 1400

100%/x%=1400/311.43
(100/x)*x=(1400/311.43)*x       - we multiply both sides of the equation by x
100=4.4953922229715*x       - we divide both sides of the equation by (4.4953922229715) to get x
100/4.4953922229715=x
22.245=x
x=22.245

now we have:
311.43 is 22.245% of 1400
