15 if you use the tree method the you would do 1 2 & 3 and you would put the 5 routes from the library to her home  on each number and get the answer

Answer 2

Answer: There are 15 routes from Ruth Ann's school to her home with a stop at the library

Step-by-step explanation:

Since we have given that

Number of routes she can choose Ruth Ann from to get from school to the library = 3

Number of routes she can choose Ruth Ann from to get from the library to her home = 5

Number of routes from Ruth Ann's school to her home with a stop at the library is given by

`3* 5=15`

Hence, there are 15 routes from Ruth Ann's school to her home with a stop at the library.
