Math Problem of the Week - Middle School - July 4, 2021 to July 10, 2021

Middle School: 

Question: Jack's science homework is to measure the temperature outside at 7 pm each day for a week. On Monday, his thermometer reads 77°F, but his homework asks for the temperature in Celsius. Since the temperature in Celsius is equal to five-ninths of the quantity 32 less than the temperature in Fahrenheit, what should Jack write down on his homework? 

Answer: 25°C

Solution:  We need to find five-ninths of 32 less than 77. First, we subtract 32 from 77 to get 45. Next, we find five-ninths of 45. Since one-ninth of 45 is 5, five-ninths of 45 is 5 × 5 = 25. So, Jack should write down 25°C on his homework.
