To multiply or divide fractions with negative numbers, you can follow these steps:
1. Convert the negative number(s) to their proper fraction form. To do this, write the negative number as a fraction with a negative numerator and a positive denominator. For example, -2 would become (-2/1).
2. Determine the sign of the final result. If the signs of the fractions being multiplied or divided are the same, the result will be positive. If the signs are different, the result will be negative.
3. Multiply or divide the fractions as you normally would without considering the signs. Multiply the numerators together and the denominators together for multiplication, or multiply the first fraction by the reciprocal (flipping the numerator and denominator) of the second fraction for division.
4. Simplify the resulting fraction, if necessary, by reducing the numerator and denominator to their lowest terms.
5. Apply the sign determined in Step 2 to the resulting fraction to get the final answer.
Let's go through an example:
Example 1: Multiply -2/3 by -4/5
1. Convert the negative numbers to proper fractions: (-2/1) and (-4/1).
2. The signs are different, so the result will be negative.
3. Multiply the numerators: (-2) * (-4) = 8
Multiply the denominators: (3) * (5) = 15
4. The resulting fraction is 8/15, which is already simplified.
5. Apply the negative sign: -8/15 is the final answer.
Remember, when dividing, you will need to flip the second fraction and proceed with multiplication as shown in Step 3.
I hope this explanation helps you understand how to multiply and divide fractions with negative numbers!
