Answer:

The expression to show the average daily change in temperature can be given by :

⇒ \frac{2.64-0.22-0.35+0.63}{4}°C

Step-by-step explanation:

Changes in the temperature of city as reported by newspaper :

Day 1: 2.64° C

Day 2: -\frac{2}{9}°C

Day 3: -0.35°C

The average daily change in temperature can be calculated as

⇒ \frac{2.64-\frac{2}{9}-0.35+\frac{5}{8}}{4}°C

The fractions can be written in decimals

⇒ \frac{2.7}{4}°C

⇒ 0.675\°C\approx 0.68°C [Average daily change in temperature.]
