If you had an apple and you cut it into $2$2 equal pieces to share with a friend, how much would each of you get? You would each get half an apple. One half is an example of a number that is less than one whole. It can be written as $\frac{1}{2}$12 as a fraction or $0.5$0.5 as a decimal.
We can express a part of a whole in words, or we can use numbers and symbols (e.g. fractions or decimals).
