4.38 is what percent of 49 - 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 49 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 49, so we can write it down as 100%=49.
4. We know, that x% equals 4.38 of the output value, so we can write it down as x%=4.38.
5. Now we have two simple equations:
1) 100%=49
2) x%=4.38
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%=49/4.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.38 is what percent of 49

100%/x%=49/4.38
(100/x)*x=(49/4.38)*x       - we multiply both sides of the equation by x
100=11.187214611872*x       - we divide both sides of the equation by (11.187214611872) to get x
100/11.187214611872=x
8.9387755102041=x
x=8.9387755102041

now we have:
4.38 is 8.9387755102041% of 49
