When you woke up this morning, the temperature was -3.4°c. at bedtime, the temperature was 1.7°c. which expression and statement describes the situation? -3.4> 1.7, so -3.4°c is warmer than 1.7°c. 1.7=12(-3.4), so 1.7°c is half as cold as -3.4°c. 1.7> -3.4, so 1.7°c is warmer than -3.4°c. 1.7< -3.4, so 1.7°c is colder than -3.4°c.
