Multiplying rational numbers

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

When you multiply two negative numbers, the result is a positive number.

The product of a positive number and a negative number is a negative number.

To multiply fractions, multiply the numerators together and the denominators together.

The result is -3.

To convert an improper fraction to a mixed number, divide the numerator by the denominator and express the remainder as a fraction.

The first step is to find a common denominator.

The fraction 4/15 is already in its simplest form, as there are no common factors between 4 and 15.

The result is -1/8.

Identify the quantities involved, determine the operation needed (addition, multiplication, etc.), and apply the appropriate mathematical rules.
