let the numbers are A and B
A×B = -14/15
A = 2/9
B = (-14/15)/(2/9) = -14/15 × 9/2 = (-14×9)/(15×2) = (-7×3)/(5) = -21/5
other number is -21/5

→ product of two rational number is -14/15
→ if one number is 2/9
→ let other number be x
→ x×2/9= -14/15
→ 2x/9 = -14/15
→ 2x = -14/15 ×9
→ 2x = -126×15
→ x = -21/5
