1. We assume, that the number 250 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 250 is 100%, so we can write it down as 250=100%.
4. We know, that x is 24% of the output value, so we can
write it down as x=24%.
5. Now we have two simple equations:
1) 250=100%
2) x=24%
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:
250/x=100%/24%
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 24% of 250
250/x=100/24
(250/x)x=(100/24)x
- we multiply both sides of the equation by x
250=4.16666666667*x
- we divide both sides of the equation by (4.16666666667) to get x
250/4.16666666667=x
60=x
x=60
now we have:
24% of 250=60
