Question

there are 8 students who have 3/4 of a cake they want to share how much of the cake will each person gets if they split it evenly

Answer 1

You have 3/4 divided by 8 or 8/1

3/4 ÷ 8/1
3/4 x 1/8 = 3/32

Each person gets 3/32 of the original cake.

Here's another way to think of it:
Each person gets 1/8 of 3/4, so you multiply 1/8 times 3/4
