Answer:
4 1/2 because you need to multiply 3/4 by 6 and you can also add 3/4 to itself 6 times which will also give you 4 1/2
Explanation:
I used a calculator and then checked it by doing it on paper
4 1/2 hours
To find how long, multiply the length of time in hours by the number of cakes. 1 cake takes 3/4 of a an hour so 6 cakes will take
3/4 * 6 = 18/4 = 4 2/4
4 2/4 simplifies to 4 1/2 hours.
