What is 1400 percent of 21.5 - 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 21.5 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 21.5 is 100%, so we can write it down as 21.5=100%.
4. We know, that x is 1400% of the output value, so we can write it down as x=1400%.
5. Now we have two simple equations:
1) 21.5=100%
2) x=1400%
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:
21.5/x=100%/1400%
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 1400% of 21.5

21.5/x=100/1400
(21.5/x)*x=(100/1400)*x       - we multiply both sides of the equation by x
21.5=0.071428571428571*x       - we divide both sides of the equation by (0.071428571428571) to get x
21.5/0.071428571428571=x
301=x
x=301

now we have:
1400% of 21.5=301
