Unlike continual multiplication, which offers you a larger number...

*

Unlike continuous multiplication, which provides you a larger number...multiplying fractions will certainly usually give you a smaller number.

So when we multiply 1/2 times 2/4...

*

So when we main point 1/2 times 2/4...our answer will be smaller sized than 2/4.

*

Here's an additional example. Let's say you have actually 3/5 of a cup of coco filling.
