Answer: Hello there!
We know that Katie completes 2/3 of a craft project in 3/4 of an hour.
We want to know which fraction of the project Katie completes in one hour.
Ok, you can think this in a next way:
2/3 project = 3/4 hours
now we divide by 3/4 (or multiply by 4/3) in both sides:
(2/3)*(4/3) project = (3/4)(4/3) hours
8/9 project = 1 hour
So in one hour, she does 8/9 of the craft project.
