Main Idea/Vocabulary Use the rules for dividing integers.

Key Concept

Example 1 Divide Integers with Different Signs Find 51 ÷ (–3). 51 ÷ (–3) = –17The integers have different signs. The quotient is negative. Answer: –17

Example 1 CYP A.156 B.13 C.–13 D.–156 Find 169 ÷ (–13).

Example 2 Divide Integers with Different Signs The integers have different signs. The quotient is negative. Find. Answer: –11

Example 2 CYP A.31 B.17 C.–17 D.–31

Key Concept 3

Example 3 Divide Integers with the Same Sign Find –12 ÷ (–2). –12 ÷ (–2) = 6The integers have the same sign. The quotient is positive. Answer: 6

Example 3 CYP A.–40 B.–4 C.4 D.40 Find –32 ÷ (–8).

Example 4 ALGEBRA Evaluate –18 ÷ x if x = –2. Divide Integers with the Same Sign –18 ÷ x = –18 ÷ –2 Replace x with –2. = 9Divide. The quotient is positive. Answer: The solution is 9.

Example 4 CYP A.–60 B.–9 C.9 D.48 Evaluate –54 ÷ x if x = –6.

Example 5 FINANCIAL LITERACY An October newspaper headline read that the total value of stocks held by Japanese financial institutions dropped from $987 billion to $900 billion in 6 weeks. What was the average change in value per week? Y is the value of the stocks after 6 weeks, X is the initial value of the stocks. Answer: The average change in value was –$14.5 billion per week. Divide.

Example 5 CYP A.–3ºF B.3ºF C.4ºF D.12ºF TEMPERATURE The temperature in Miami was 82ºF at 9:00 A.M. Four hours later the temperature was 94ºF. What was the average change in temperature per hour?
