PDF Multiplication with Fractions

Rules for multiplying two rational numbers • Before you begin you should review rules for multiplying positive and negative rational numbers – Positive * Positive =Positive (1 *1=1) – Negative * Negative = Positive (-1 *-1=1) – Positive * Negative = Negative (1*-1= -1) – Negative * Positive = Negative (-1*1= -1)

  • What is the multiplication of positive and negative numbers?

    Positive - Negative = Positive Negative - Negative = Negative + Positive • use the larger number and its sign, subtract Multiplication (x) Positive x Positive = Positive Negative x Negative = Positive Negative x Positive = Negative Positive x Negative = Negative • change double negatives to a positive Division (÷) Positive ÷ Positive = Positive

  • What is the identity element of multiplication?

    To understand this, we need to consider the identity element of multiplication: Whenever the same non-zero number appears in both the numerator and denominator, the fraction is equal to 1. , 1 1 , and even 1 . The number 1 is the identity element of multiplication. That means whenever we multiply a number by 1, we get the same number.

  • Which fraction has a negative exponent?

    In this example, the negative exponent is in the denominator of the fraction. Hence, 1/2 -3 is equal to 8. The fractions with negative exponents are solved using the two above-mentioned rules. Now, let us consider the example, x 2 /x -3 Here, the numerator has a positive exponent and the denominator has a negative exponent.

  • What happens if you make a negative fraction?

    It’s important to note here that only either the numerator or denominator should be negative. This makes the entire value negative. Instead, if you make both negative, the fraction itself will turn positive since -1/-1 = 1. Any negative fraction is any fraction multiplied by -1. How to calculate a negative fraction? This is x in the formula above.
