To find the average daily change in temperature, we need to divide the sum of the temperature changes by the number of days.
Let's represent the temperature changes as follows:
Day 1: 3.24 degrees Celsius
Day 2: -3/8 degrees Celsius
Day 3: -0.15 degrees Celsius
Day 4: 7/9 degrees Celsius
We can write the expression as:
(3.24 + (-3/8) + (-0.15) + (7/9)) / 4.
Calculating this expression:
(3.24 + (-0.375) + (-0.15) + (0.778)) / 4 ≈ 3.49375 / 4 ≈ 0.87344.
Therefore, the rounded expression for the average daily change in temperature is approximately 0.87 degrees Celsius.
A newspaper reports the following changes in the temperature of a city over 4 days:
3.24 degrees Celsius, negative 3 over 8 degrees Celsius, −0.15 degrees Celsius, 7 over 9 degrees Celsius
Write an expression to show the average daily change in the temperature of the city.
(P.S, please write it with the answer rounded to the nearest hundredth)
