TextAddition and Subtraction of Rational NumbersAssociative Property of Rational Numbers

\left(\frac{-3}{5}\times\frac{4}{7}\right)\times\frac{-1}{2}=\frac{-3}{5}\times\left(\frac{4}{7}\times\frac{-1}{2}\right) is an example of:

The value of \frac{-5}{8}+\frac{7}{12} is:

Assertion (A): Division of rational numbers is not commutative. Reason (R): Division of rational numbers is not associative.

For all non-zero rational numbers a, b, c: (a \div b) \div c = a \div (b \div c).

Using suitable rearrangement, find: \frac{3}{7}+\frac{-6}{11}+\frac{-8}{21}+\frac{5}{22}

What number should be added to \frac{-5}{12} to get \frac{3}{8}?
