QUICK CONCEPT REVIEW
When a whole object or group is divided into equal parts, then each part is called a fraction of that whole.
Suppose, there is an apple and you want to divide it equally among 2 friends then equal pieces of the apple form fractions.
A fraction is a part of a whole divided in equal parts.
PROPERTIES OF FRACTION
For example: \[\frac{1}{4}=\frac{1}{4}\times \frac{3}{3}=\frac{3}{12}\]
So, \[\frac{1}{4}\] and\[\frac{3}{12}\]are equivalent fractions.
TYPES OF FRACTIONS
Let us now understand different kinds of fractions. Fractions can be divided into two categories:
Like Fractions are those fractions which have the same denominators.
\[\frac{1}{9},\frac{2}{9},\frac{3}{9},\frac{5}{9},\frac{6}{9}\]Etc. is all like fractions
Unlike Fractions are those fractions which have different denominators.
\[\frac{1}{3},\frac{2}{13},\frac{4}{9},\frac{5}{8},\frac{6}{11}\] are all unlike fractions.
Proper Fractions are those fractions in which the numerator is less than the denominator.
\[\frac{1}{2},\frac{2}{3},\frac{4}{5},\frac{6}{7},\frac{8}{9},\frac{9}{11}\]are all proper fractions.
Improper Fractions are those fractions in which the numerator is greater than the denominator,
\[\frac{3}{2},\frac{8}{5},\frac{7}{4},\frac{12}{10}\] are improper fractions.
Games
Take paper cut outs of basic shapes like circle, square and rectangle. Now fold the paper to get equal parts. It's time to cooer. Color half quarter, one third of different shapes
