Example 2-1a Replace the with < or > to make –9 –5 a true sentence. Write the problem using a circle for the comparison - 9 - 5 We know that 9 is larger than 5 but when they are negative the inverse is true We can see this on a number line Plot - 9 Answer: –9 < –5 Plot - 5 1/2
Example 2-1b Replace the with < or > to make –3 –6 a true sentence. Answer: –3 > –6 1/2
MULTIPLE-CHOICE TEST ITEMThe lowest temperatures in Europe, Greenland, Oceania, and Antarctica are listed in the table. Order the temperatures from least to greatest. Continent Record Low Temperature (°F) A –67, –87, 14, –129 B 14, –67, –87, –129 C –129, –87, –67, 14 D –67, –87, –129, 14 Europe –67 Greenland –87 Oceania 14 Antarctica –129 Example 2-2a 2/2
Continent Record Low Temperature (°F) Europe –67 Greenland –87 Oceania 14 Antarctica –129 Example 2-2a Begin with the negative numbers Remember: The bigger a number looks, the smaller it is when it is negative Negative 129 is the smallest number Negative 87 is the next smaller number -129, -129, -87, -129, -87, -67, Negative 67 is the next smaller number 2/2
Continent Record Low Temperature (°F) Europe –67 Greenland –87 Oceania 14 Antarctica –129 Example 2-2a 14 is the only number remaining that has not been used Choose the appropriate answer A –67, –87, 14, –129 B 14, –67, –87, –129 C –129, –87, –67, 14 D –67, –87, –129, 14 -129, -129, -87, -129, -87, -67, -129, -87, -67, 14 Answer: C 2/2
