Express each of the ratio in its simplest form:
dozen to a score (Note: A Score = 20)

Answer

To express the ratio of dozen to a score in its simplest form, follow these steps:

### Step 1: Understand the values
A dozen is equal to 12, and a score is equal to 20.

### Step 2: Write the ratio
The ratio of dozen to a score can be written as:
\[ \text{Ratio} = \frac{\text{Dozen}}{\text{Score}} = \frac{12}{20} \]

### Step 3: Simplify the ratio
To simplify the ratio, we need to divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 12 and 20 is 4.

### Step 4: Divide both parts by the GCD
Now, divide both the numerator and the denominator by 4:
\[ \frac{12 \div 4}{20 \div 4} = \frac{3}{5} \]

### Step 5: Write the final ratio
Thus, the ratio of dozen to a score in its simplest form is:
\[ 3 : 5 \]
