0.04% x 80 =? Find it
Answers
Answer:
0.032
Step-by-step explanation:
1. We assume, that the number 80 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 80 is 100%, so we can write it down as 80=100%.
4. We know, that x is 0.04% of the output value, so we can write it down as x=0.04%.
5. Now we have two simple equations:
1) 80=100%
2) x=0.04%
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:
80/x=100%/0.04%
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 0.04% of 80
80/x=100/0.04
(80/x)*x=(100/0.04)*x - we multiply both sides of the equation by x
80=2500*x - we divide both sides of the equation by (2500) to get x
80/2500=x
0.032=x
x=0.032
now we have:
0.04% of 80=0.032
