Q. The list below shows the temperature Bao recorded at 1111:0000 p.m. for four days last January.\newlineMonday: 7F -7^{\circ} \mathrm{F} \newlineTuesday: 0F 0^{\circ} \mathrm{F} \newlineWednesday: 7F 7^{\circ} \mathrm{F} \newlineThursday: 25F -25^{\circ} \mathrm{F} \newlineOn which of the days did Bao record the lowest (coldest) temperature?\newlineMonday\newlineTuesday\newlineWednesday\newlineThursday
  1. Find Lowest Temperature: To find the lowest temperature, we need to compare the temperatures recorded on each day.\newlineMonday: 7°F-7\degree F\newlineTuesday: 0°F0\degree F\newlineWednesday: 7°F7\degree F\newlineThursday: 25°F-25\degree F\newlineWe look for the smallest number, which will be the most negative number since we are dealing with temperatures in degrees Fahrenheit.
  2. Compare Temperatures: Comparing the temperatures:\newline7-7°F is colder than 00°F and 77°F, but we need to check if it's colder than 25-25°F.\newline00°F is warmer than 7-7°F and 25-25°F, and it's colder than 77°F.\newline77°F is the warmest temperature on the list.\newline25-25°F is colder than 7-7°F, 00°F, and 77°F.\newlineTherefore, 25-25°F is the lowest temperature recorded.
