∙ 7y agoWe write .5 or 0.5 as the decimal for one half.
Decimals can be "terminating" "recurring" or "other." A terminating decimal is one which is finite. Recurring and other decimals continue on forever. For instance 0.5 is a terminating decimal. 0.729 is a terminating decimal. 0.3333333... is not a terminating decimal. pi (3.1415926535....) is not a terminating decimal.
12 and one half as a decimal is 12.5
A terminating decimal is a decimal representation written with a repeating final 0, that is said to end before these zeros. For example, instead of 1.500000..., one would simply write 1.5 without the infinite zeros at the end. In this case, 1.5 is said to be a "terminating decimal number".
