Jill records the temperature outside every hour for 4 hours. She finds that the temperature dropped by the same amount each hour. After 4 hours, she finds that the temperature dropped a total of 20βF. She writes this number sentence.
(β20)Γ·4=β5
What does the number sentence mean?
The total drop in temperature, β20βF, divided by 4 hours equals β5βF per hour. The temperature dropped 5βF each hour.
The total number of drops, 20, divided by 4 hours equals 5 times per hour. The temperature dropped 5 times per hour.
The total number of hours, 20, divided by 4βF equals 5 hours. The temperature dropped once every 5 hours.
The total drop in temperature, β20βF, divided by 4βF in the first hour, equals β5 drops. The temperature dropped 5 times.
