Your answer is -
1. We assume, that the number 14.5 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 14.5 is 100%, so we can write it down as 14.5=100%.
4. We know, that x is 228% of the output value, so we can write it down as x=228%.
5. Now we have two simple equations:
1) 14.5=100%
2) x=228%
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:
14.5/x=100%/228%
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 228% of 14.5
14.5/x=100/228
(14.5/x)*x=(100/228)*x - we multiply both sides of the equation by x
14.5=0.438596491228*x - we divide both sides of the equation by (0.438596491228) to get x
14.5/0.438596491228=x
33.06=x
x=33.06
now we have:
228% of 14.5=33.06
