Based on your comment I assume you want to find 7,533 subtracted by 7,200. To estimate this, round 7,533 to the hundreds place, so 7,533 becomes 7,500.

7,500 - 7,200 = 300, using mental math.

malfutka [58]

Answer: -5 degrees Celsius

Step-by-step explanation:

Temp at 2:00am = -2.7

During that time the temperature has risen by 1.15 degrees every hour so has risen in total by:

-2.7-2.3=-5

It was -5 degrees at midnight
