Answer:

The answer is 5.6

Explanation:

1. We assume, that the number 70 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 70 is 100%, so we can write it down as 70=100%.

4. We know, that x is 8% of the output value, so we can write it down as x=8%.

5. Now we have two simple equations:

1) 70=100%

2) x=8%

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:

70/x=100%/8%

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 8% of 70

70/x=100/8

(70/x)*x=(100/8)*x - we multiply both sides of the equation by x

70=12.5*x - we divide both sides of the equation by (12.5) to get x

70/12.5=x

5.6=x

x=5.6

now we have:

8% of 70=5.6
