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

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

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

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.

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

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

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

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

2)
