Answer:
0.0004
Step-by-step explanation:
1. We assume, that the number 0.16 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 0.16 is 100%, so we can write it down as 0.16=100%.
4. We know, that x is 0.25% of the output value, so we can write it down as x=0.25%.
5. Now we have two simple equations:
1) 0.16=100%
2) x=0.25%
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:
0.16/x=100%/0.25%
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 0.25% of 0.16
0.16/x=100/0.25
(0.16/x)*x=(100/0.25)*x - we multiply both sides of the equation by x
0.16=400*x - we divide both sides of the equation by (400) to get x
0.16/400=x
0.0004=x
x=0.0004
now we have:
0.25% of 0.16=0.0004
