The reason that why these temperatures are related because when we start counting the numbers from left, it becomes smaller. For ex- 3 is on the left of 5. So, 3 is smaller than 5. That's how when we start counting from the left in negative numbers, the negative numbers gets smaller.
Since ms. watson’s class read for a total of 450 hours, we can calculate the amount of hours the mr gerk’s class read by: 450*2/3, which equals 300. Then we know Miss rupp’s class read twice the number of hours read by mr. gerk’s class so that’s 600 hours.
