Answer 2

Answer:

$\huge\underline{ \underline{ \red{your \: \: answer}}}$

Step-by-step explanation:

$\sf\red{5 \: rational \: numbers \: between - 2 \: and \: - 3} \\ \sf\blue{ \frac{ - 2 \times 6}{6} = \frac{ - 12}{6} } \\ \sf\red{ \frac{ - 3 \times 6}{6} = \frac{ - 18}{6} } \\ \sf\green{5 \: rational \: numbers \: between \: - 2 \: and - 3}\\ \sf\orange{are = \frac{ - 13}{6,} \frac{ - 14}{6}, \frac{ - 15}{6}, \frac{ - 16}{6}, \frac{ - 17}{6} }$
