Decimals: Decimals are numbers that are written with a decimal point. They are used to express parts of a whole. For example, 0.5 is equal to 1/2 or one half. Tenths: Tenths are a way of expressing fractions. It is written as a decimal with one place to the right of the decimal point. For example, 0.1 is equal to 1/10 or one tenth. Hundredths & Thousandths: Hundredths and Thousandths are two more ways of expressing fractions. Hundredths are written as a decimal with two places to the right of the decimal point, and thousandths are written as a decimal with three places to the right of the decimal point. For example, 0.01 is equal to 1/100 or one hundredth, and 0.001 is equal to 1/1000 or one thousandth.

Did you know that a fraction and its decimal form have an infinite number of possible equivalents? For example, 0.2 is the same as 1/5, 2/10, 4/20 and so on. The number 0.999... (an infinite string of nines) is actually equal to 1 in decimal form, but it’s equal to 1/3 when written as a fraction. The number 0.3333... (an infinite string of threes) is actually equal to 1/3 when written as a fraction, but it’s equal to 1 in decimal form.
