To write the ratio of mechanical pencils to regular pencils, we first identify the quantities:
- Mechanical pencils: 3
- Regular pencils: 6
The ratio is given by:
\[ \text{Ratio of mechanical pencils to regular pencils} = \frac{\text{Mechanical pencils}}{\text{Regular pencils}} = \frac{3}{6} \]
To express this ratio in simplest form, we can divide both the numerator and the denominator by their greatest common divisor, which is 3:
\[ \frac{3 \div 3}{6 \div 3} = \frac{1}{2} \]
Thus, the ratio of mechanical pencils to regular pencils in simplest form is 1 to 2.
Answer:
The ratio of mechanical pencils to regular pencils is 1 to 2.
