What are fractions?
Fractions numerically represent sections or parts of one whole,
when it is divided into
equal sections or parts.
When writing fractions, you write the number representing the part being referred to
above a line and the total number of parts that make up the whole below it.
The one above is the numerator and the one below is the denominator.
The line between the two numbers is called vinculum and it represents "divided by"
or "of&rdquo, as in one of four parts or
^{1}/_{4} , two of three sections or
^{2}/_{3}, etc.
With this in mind, the denominator cannot be zero, because you cannot divide anything into zero parts.
The best way to illustrate fractions is by drawing the whole and dividing it into parts.
One-half or or
½ means one of two parts that make up the whole,
when it is divided into two equal parts.
One-third or
^{1}/_{3} means one of two parts that make up the whole,
when it is divided into two equal parts.
One-fourth or
¼ means one of four parts that make up a whole,
when it is divided into four equal parts.
And so on&hellip
Fractions can be represented in other shapes, too.
The best example of simple fractions is pizza.
Like in the image above, the pizza is divided into eight parts or slices. If you eat one slice, that means you ate
^{1}/_{8} (one-eighth) of the pizza. If you eat 2 slices, that makes it
^{2}/_{8} (two-eighths), and so on.
Ideally, that pizza should be sliced into eight equal parts so the slices are true representations
of one-eighth of the pizza, but you get the idea.
