1 AGENDA TICKET IN THE DOOR TICKET IN THE DOOR CORNELL NOTES ON DIVIDING RATIONAL NUMBERS GUIDED PRACTICE WRAP UP(Kahoot) 26*(-12) 9*(-23) (-125)*(-2) -2(6+9)

2 Dividing Rules 1) If the numbers have the same signs then the quotient is positive. -32 ÷ (-8 )= 4 2) If the numbers have different signs then the quotient is negative. 81 ÷ (-9) = -9

3 When dividing two negative numbers, the quotient is positive.
True False Answer Now

4 When dividing a negative number and a positive number, use the sign of the larger number.
True False Answer Now

5 The reciprocal of a number is called its multiplicative inverse.
The reciprocal of is where a and b  0. The reciprocal of a number is called its multiplicative inverse. A number multiplied by its reciprocal/multiplicative inverse is ALWAYS equal to 1.

6 Example #1 The reciprocal of is Example #2 The reciprocal of -3 is

7 Basically, you are flipping the fraction!
We will use the multiplicative inverses for dividing fractions.

8 Which statement is false about reciprocals?
Reciprocals are also called additive inverses A number and its reciprocal have same signs If you flip a number, you get the reciprocal The product of a number and its reciprocal is 1 Answer Now

9 Examples 1) When dividing fractions, change division to multiplying by the reciprocal.

10 2)
