Step-by-step explanation:

let \: other \: number \: be \: x \:  \\ then \\ x + 3 \times ( \frac{ - 5}{2} ) =  \frac{2}{7}  \\ x + ( \frac{ - 15}{2} ) =  \frac{2}{7}  \\ x =   - (\frac{ - 15}{2} ) +  \frac{2}{7}  \\ x =  \frac{15}{2}  +  \frac{2}{7}  \\ x =  \frac{105 + 4}{14}  \\ x =  \frac{109}{14} \\ x = 7 \frac{11}{14}
