Answer 1

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

$2.75 - 2.5 = 0.25$
