You buy a dozen donuts, and you and your friend each take 1/2, then another friend takes 2/3 of yours. How many do you have left? What is 2/3 of 1/2 of 12? Learn the easy way to multiply fractions!
At the baseball game, you and your friend each order a pizza. The pizzas are the same size, but sliced differently. Your pizza is cut into 12 slices and your friend’s pizza is cut into 8 slices.
When adding and subtracting fractions, you count the same-size parts by having a common denominator.
When multiplying fractions, the sizes of the parts change. You are taking part of a part of something.
