When we learn the basic math operations, we start by dealing with the operations on integers. But the world is full of partial amounts of things… A half cup of sugar in a recipe or a slice of pizza or a quarter dollar. All of these represent a portion of a whole, and that’s exactly what a fraction is. We deal with partial amounts every day, so these ideas are familiar even if the way we have to work with them in math at first seems a little intimidating. Don’t worry! We’ll make it easy!
Here's a useful tool...
