Fractions are pieces of some item, shown in mathematics as the number of pieces (the top number) and how many pieces the whole item has been divided into (the bottom number.)

For instance, 1/4 or one fourth, is one piece out of four total available pieces.

9/10, or nine tenths, is nine out of a total ten pieces.

The item could be actually divided, like a pizza, but could also just be measured. You could say, "my puppy dog has achieved 2/3 of his adult size." Meaning that if he grows half of his current size more, he will be adult size. Half of his current size = 1/3 of an adult size, so 2/3 (what he is now) + 1/3 (how much he needs to grow) = 3/3 (the adult size).

3/3 or three thirds is all of the "pieces" of the adult dog size, so it equals one, which is the whole adult dog size.

Many times people say "a fraction of..." when they mean just a small amount or piece of something. This is not used in mathematics, but in general conversation. For example, "I bought this dress for a fraction of the cost," meaning that they paid a lot less for it than it originally sold for.

Fractions are parts of a whole. There are two numbers that represent a fraction. For example if you are talking about a cake which is cut into 5 equal pieces, and two of those pieces have been eaten, you would say that 2/5 of the cake is missing, and 3/5 are left.

The top number is called the numerator - (the number of parts)

The bottom number is called the denominator (the total number of parts that make up the whole thing)

Fractions are part of a whole. You can eat a whole pizza, with eight slices; that is represented by 8/8, which equals one--8 out of 8 is the whole thing.

If you eat a part of the pizza, you are eating a fraction of it. If you eat half of it (1/2), you will have eaten four slices, which is 4/8 (4 out of 8). The fraction 4/8 is equal to 1/2.

Fractions are pieces of a whole. Can you visualize a fraction in math, such as 1/5? See it this way, visualize a mirror broken into five pieces. Each piece is still a mirror but each piece is also only part of the whole mirror so if you pick up one piece of the mirror you will be holding one 1/5th of said mirror.

...A fraction is just a part of a number. For instance half of 5 can be written as a fraction 5/2. This is equivalent to dividing 5 by 2.

...Fractions are basically percentages or decimals. Except it is a number over a hundred.

For example: 1/10 is 10% or .1
