Let’s break down the math behind “1 2 of 5” and see how you can use it in different contexts.
### Calculating the Fraction
The general form is: [ \text{Fraction} = \frac{\text{Numerator}}{\text{Denominator}} ]
For “1 2 of 5,” the numerator is 1, the denominator is 5. So: [ \frac{1}{5} = 0.20 ] or [ 0.
### Converting to a Percentage

- 1/2 = 50 %
- 1/3 ≈ 33 %
- 1/4 = 25 %
- 1/5 = 20 %
- 1/10 = 10 %
