What is the rule for determining the sign of the product of two fractions?

It is the same as determining the sign of the product of two integers;
+ x + = +
+ x - = -
- x + = -
- x - = +
OR
If only positive numbers are multiplied, the result is positive.
If positive and an even number of negative numbers (for example, + x - x -) are multiplied, the result is positive.
If positive and an odd number of negative numbers (for example, + x + x -) are multiplied, the result is negative.
If an even number of negative numbers (for example, - x -) are multiplied, the result is positive.
If an odd number of negative numbers (for example, - x - x -) are multiplied, the result is negative.
Remember the rule:
Product of a positive and a positive fraction is always positive.
Product of a positive and a negative fraction is always negative.
Product of a negative and a positive fraction is always negative.
Product of a negative and a negative fraction is always positive.
Examples:
½ * ¼ = 1/8
½ * -¼ = -1/8
-½ * ¼ = -1/8
-½ * -¼ = 1/8

What are three rules you can use to compare fractions?
Rule #1 When two fractions have the same denominator, the bigger fraction is the one with the bigger numerator. Rule # 2 When comparing fractions that have the same numerator, the bigger fraction is the one with the smaller denominator. Rule # 3 You can convert the fractions and then just put the greater than, less than or equal to sign to see what the comparison is between the fractions.

How do i divide fractions with a number in from of the fraction?
You have to make the fractions improper then you switch the devision sign to the multiplying sign and then you switch the numbers around on the second fraction then you just multiply the fractions. When ever you do this think keep switch flip you keep the first fraction alone you switch the sign then you flip the last fraction. Good luck 😍
