​

Answer 1

Step-by-step explanation:

Given

• sum of two rational number = -4/9
• one of them = 13/6
• let second number be x

$\frac{13}{6} + x = \frac{ - 4}{ \: \: 9} \\ \frac{ - 4}{ \: \: 9} - \frac{13}{6} \\ \frac{ - 8 - 39}{18} (lcm \: of \: 6and9 = 18) \\ \frac{ - 47}{ \: \: 18} = - 2 \frac{ - 11}{18}$
