What is 90.7 percent of 54 - 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 54 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 54 is 100%, so we can write it down as 54=100%.
4. We know, that x is 90.7% of the output value, so we can write it down as x=90.7%.
5. Now we have two simple equations:
1) 54=100%
2) x=90.7%
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:
54/x=100%/90.7%
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 90.7% of 54

54/x=100/90.7
(54/x)*x=(100/90.7)*x       - we multiply both sides of the equation by x
54=1.1025358324146*x       - we divide both sides of the equation by (1.1025358324146) to get x
54/1.1025358324146=x
48.978=x
x=48.978

now we have:
90.7% of 54=48.978
