What does 12 1/2 of 80 equal

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 12.5% of the output value, so we can write it down as x=12.5%.

5. Now we have two simple equations:

1) 80=100%

2) x=12.5%

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%/12.5%

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 12.5% of 80

80/x=100/12.5

(80/x) * x = (100/12.5) * x - we multiply both sides of the equation by x

80=8*x - we divide both sides of the equation by (8) to get x

80/8=x

10=x

x=10

now we have:

12.5% of 80=10

12 1/2 of 80 equals 56
