Question

0.04% x 80 =? Find it​

Answer 1

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
