24 is what percent of 42.78 - 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 42.78 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 42.78, so we can write it down as 100%=42.78.
4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.
5. Now we have two simple equations:
1) 100%=42.78
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:
100%/x%=42.78/24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24 is what percent of 42.78

100%/x%=42.78/24
(100/x)*x=(42.78/24)*x       - we multiply both sides of the equation by x
100=1.7825*x       - we divide both sides of the equation by (1.7825) to get x
100/1.7825=x
56.100981767181=x
x=56.100981767181

now we have:
24 is 56.100981767181% of 42.78
