Answer:
5%
Step-by-step explanation:
1. We assume, that the number 48 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 48, so we can write it down as 100%=48.
4. We know, that x% equals 2.4 of the output value, so we can write it down as x%=2.4.
5. Now we have two simple equations:
1) 100%=48
2) x%=2.4
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%=48/2.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 2.4 is what percent of 48
100%/x%=48/2.4
(100/x)*x=(48/2.4)*x - we multiply both sides of the equation by x
100=20*x - we divide both sides of the equation by (20) to get x
100/20=x
5=x
x=5
now we have:
2.4 is 5% of 48
