Question

Find the unit rate if suzie reads 45 books in 15 days
​

Answer 1

Explanation:

she reads 45 books in 15 days.

so, the reading rate is 45/15.

now, a ratio is just a fraction with a special meaning, but calculations, simplifications and so on are all the same.

so,

45/15 = 9/3 = 3/1 = 3

that means she reads 3 books in 1 day.
