Fractions can be converted to a denominator of a power of ten:.

It is often more useful to work with numbers in the form of decimals than fractions. It is possible to convert fractions to decimals by (i) converting the denominator to a power of ten, or (ii) by using equivalent fractions or (iii) by using division. Understanding that the place to the right of the decimal point is the tenths place makes it immediately clear that, for example, There is a 10-to-1 relationship between the value of any two adjacent places in a number.īy applying place value it is simple to convert from a decimal to fraction. Place value materials can be used to support students to develop conceptual links between fractions and decimals.įor example, the following representation shows both 1.43 and 1+ 4/10 + 3/100

Changing a decimal into a fraction is just a different way of expressing the same number. Since decimals contain fractional parts, they can also be written as fractions. The decimal 0.875 is read as “eight hundred seventy-five thousandths” because the last digit, 5, is in the thousandths place. We say “twenty-five hundredths” because the last digit, 5, is in the hundredths place. Since 25 comes after the decimal point, this is the fractional part of the number. The decimal 5.25 is read as “five and twenty-five hundredths”. As we move from left to right, each place value is divided by 10: 0.75 is a decimal that is less than 1.ĭecimals are based on powers of 10. In the number 0.75, the whole number part is 0, and the fractional part is. The digits that come after the decimal point show a value that is less than 1.įor instance, in the number 25.16, 25 is the whole number part, and the fractional part is. Separating these parts is a dot called a decimal point. First, a decimal is a number that has a whole number part and a fractional part. We’ll also talk about how to use these numbers in the real world.īefore we get started, let’s review a few things. Today we’ll explore the connection between decimals, fractions, and percents.
