Answer:
9/12 slices of cake or 1 and 1/2 cakes
Step-by-step explanation:
This one isn't that hard if you learn how to do it,
#1. The first cake has 3 out of 6 slices left or 3/6 after being handed out, 3 slices so keep that number in mind.
#2. The second cake still has it's full amount of slices so that means 6/6 or 1 whole cake.
#3. 12 is the total amount of cake slices that were there and you had 9 left so it's 9 slices of cake over 12 slices of cake or 9/12 slices of cake. WARNING! THIS IS HOW MANY CAKE SLICES THAT IS LEFT.
HERE IS HOW TO FIND HOW MANY CAKE IS LEFT:
#1. The first cake is half a cake so it is 3 out of 6 slices that remains, or 1/2 simplified.
#2. The second cake is cut but didn't get any taken, so it is still 1 whole cake
#3. Just add the whole amount of cake you have and there you go! You have 1 and 1/2 of cake or 1 1/2! WooHoo!
