Hi there!
If Bruce reads for 3/4 of an hour each night and he wants to know how long he'll have read in 4 nights, then we'll need to do some multiplication. We need to multiply 3/4 * 4/1. Multiply straight across to get 12/4, which simplifies to 3 hours in 4 nights.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
