Answer:
Olivia will have 1 2/3 pages typed in an hour.
Step-by-step explanation:
Olivia can type 5/12 of a page in 15 minutes. 15 minutes is a fourth of an hour, so to find out how many pages she will have written in an hour you can multiply 5/12 X 4. 5/12 X 4 equals 1 8/12, which can be simplified as 1 2/3.
Hope this helped you :)
