The following subtraction : $\frac{-5}{6}-\frac{8}{9}$ follows the closure property.

• A. True
• B. False

Answer 1

The correct option is A

True

$\frac{-5}{6}$ is a Rational number.

$\frac{8}{9}$ is also a Rational number.

The given subtraction :

$\frac{-5}{6}-\frac{8}{9}$

= $\frac{-5\times 3}{18}-\frac{8\times 2}{18}$

= $\frac{-15}{18}-\frac{16}{18}$

=$\frac{-31}{18}$ which is also a Rational number. Hence , it follows the closure property. Given statement is True.
