In this math video we will learn 6 steps to divide rational numbers in fraction form. We will discover how dividing rational numbers in fraction form are similar to dividing integers. I will introduce you to a procedural check list and graphic organizer to build your confidence and success dividing positive and negative fractions. We will begin by writing the problem and completing the following 6 steps -

Step 1: Determine the SIGN of the quotient. Write +/- in Step 6 Box.
Same Signs - The quotient of two values with the SAME sign will ALWAYS be POSITIVE
Different Signs - The quotient of two values with DIFFERENT signs will ALWAYS be NEGATIVE.

Step 2: If necessary, write mixed numbers as improper fractions.

Step 3: Rewrite division as multiplication.
1. Keep the first number the same.
2. Change the division sign to multiplication.
3. Change the second number to its reciprocal.

Step 4: Multiply the numerators.

Step 5: Multiply the denominators.

Step 6: If necessary, simplify the fraction.

Grade 7 Common Core Math
The Number System
Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
7.NS.A.2 Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
7.NS.A.2.a Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.
7.NS.A.2.b Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then –(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real- world contexts.
7.NS.A.2.c Apply properties of operations as strategies to multiply and divide rational numbers.
7.NS.A.2.d Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.
