What is 60 percent of 90.4 - 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 90.4 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 90.4 is 100%, so we can write it down as 90.4=100%.
4. We know, that x is 60% of the output value, so we can write it down as x=60%.
5. Now we have two simple equations:
1) 90.4=100%
2) x=60%
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:
90.4/x=100%/60%
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 60% of 90.4

90.4/x=100/60
(90.4/x)*x=(100/60)*x       - we multiply both sides of the equation by x
90.4=1.6666666666667*x       - we divide both sides of the equation by (1.6666666666667) to get x
90.4/1.6666666666667=x
54.24=x
x=54.24

now we have:
60% of 90.4=54.24
