Question

The lowest form of the ratio a dozen to a score is ____.

Answer 1

Finding the lowest form of the ratio:

$$\begin{gathered} 1dozen=12units \\ 1score=20units \end{gathered}$$

$\therefore$ The ratio of $12units$ to $20units$ $=\frac{12}{20}=\frac{3}{5}=3:5$ [Dividing the numerator and the denominator by $4$]

Thus, the lowest form of the ratio a dozen to a score is $3:5$.
