Charlotte reads 8 1/3 pages of a book in 10 minutes. What is her average reading rate in pages per minute?

sukhopar [10]

$8\frac{1}{3} = \frac{25}{3}$

25/3 pages of a book in 10 minutes

Multiply both numbers by the reciprocal of 10, which is 1/10

$\frac{25}{3} \times\frac{1}{10} = \frac{25}{30}=\frac{5}{6}$

$10\times\frac{1}{10}= 1$

So, Charlotte reads 5/6 pages of a book in 1 minute.
