Answer:

0.25

Step-by-step explanation:

Average means \frac{total \: number}{number \:  \: of  \: \: individuals}

According to the formula, each student in Mr. Goldwasser's class read

\frac{66}{24}  = 2.75

books on average, and each student in Mr. Welch's class read

\frac{65}{26}  = 2.5

books on average.

Therefore, the answer will be

2.75 - 2.5 = 0.25
