Percentages are another way of writing hundredths. By using division a decimal can be found.It is therefore useful to know some simple conversions between fractions and decimals.
By using equivalent fractions it is possible to convert the fraction to a simple denominator that is then easily converted to a decimal.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 Students need to develop some fraction-decimal relationships as benchmarks.ĭecimals are another way of writing fractions.īecause decimals are part of the base-ten place value system, the clearest connections between decimals and fractions occur where the denominator of a fraction is a power of ten:.Percentages are another way of writing hundredths.Decimals are another way of writing fractions.Decimals, fractions and percentages are closely related.
