Learn how to multiply three rational numbers.
In the multiplication of three or more rational numbers, the sign of
the product is positive if there is an even number of negative
rational numbers, and the sign of the product is negative if
there is an odd number of negative rational numbers.
3 8 1 = 1
4 9 2 3
The sign of the product is negative
because there are thee negative rational numbers.
2 . Multiply the rational numbers.
