What is an algorithm for multiplying rational numbers?
The algorithm is A/B * C/D = AB/CD.
When would you get a smaller product when multiplying two rational numbers?
The product of two rational numbers, X and Y, is smaller than either of them if both are between 0 and 1.
When multiplying and dividing rational numbers how do you know if you're into me positive negative?
It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.
