Answer:
x=36.772
Explanation:
1. We assume, that the number 63.4 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 63.4 is 100%, so we can write it down as 63.4=100%.
4. We know, that x is 58% of the output value, so we can write it down as x=58%.
5. Now we have two simple equations:
1) 63.4=100%
2) x=58%
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:
63.4/x=100%/58%
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 58% of 63.4
63.4/x=100/58
(63.4/x)*x=(100/58)*x - we multiply both sides of the equation by x
63.4=1.72413793103*x - we divide both sides of the equation by (1.72413793103) to get x
63.4/1.72413793103=x
36.772=x
x=36.772
now we have:
58% of 63.4=36.772
