Answer 2

Answer:

definition: closure property under addition of rational numbers:

The sum of two rational numbers is always a rational number. Thus, for any two rational numbers

$\frac{a}{b} \: and \: \frac{c}{d} = \frac{a}{b} + \frac{c}{d} .$

Step-by-step explanation:

solution:

$\frac{ - 3}{4} + \frac{2}{3} = \frac{( - 3 ) \times 3 +4 \times 2 }{4 \times 3} \\ = \frac{ - 9 + 8}{12} = \frac{ - 1}{12} .$
