![]() What is a decimal fraction and how do you teach it?ġ8. So for example, if your starting decimal value is 3.625, you'd save the "3" as a whole number, then write the fraction 625/1000 to represent everything to the right of the decimal point. How do you turn a decimal into a whole number? It contains a few examples and practice problems showing you how to do it.ġ6. This math video tutorial explains how to convert decimals to fractions. These fractions are really the same: 1 2 = 2 4 = 4 8.ġ1. Example: 5/3 (five thirds) and 9/8 (nine eighths) are improper fractions.Įquivalent Fractions have the same value, even though they may look different. In order to simplify a fraction there must be:ġ)A number that will divide evenly into both the numerator and denominator so it can be reduced.Ģ)The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number.Ī fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). "Decimal number" is often used to mean a number that uses a decimal point followed by digits that show a value smaller than one. The numbers we use in everyday life are decimal numbers, because they are based on 10 digits (0,1,2,3,4,5,6,7,8 and 9). Conversely, decimals can be used to describe long, complex and potentially infinite numbers, such as the value of pi. They do not always divide into an easy-to-express decimal. One main difference between fractions and decimals is that fractions tend to be simple expressions of ratios of whole numbers. ![]() What is difference between fraction and decimal? You can write decimal fractions with a decimal point (and no denominator), which make it easier to do calculations like addition and multiplication on fractions.Ħ. Therefore, we observe that 0.7 (decimal) is converted to 7/10 (fraction).Ī fraction where the denominator (the bottom number) is a power of ten (such as 10, 100, 1000, etc). Now in the denominator, write 1 followed by one zeros as there are 1 digit in the decimal part of the decimal number. ![]() First we will write the decimal without the decimal point as the numerator. In 0.7 we will change the decimal to fraction. The six kinds of fractions are, proper fractions, improper fractions, mixed fractions, like fractions, unlike fractions and equivalent fractions.Ĥ. In this example, 3/4, simply press "3" followed by the division symbol ("÷'") followed by 4 and then the equal sign ("=") to get your answer. Just use your calculator to divide the numerator, or the top number, of the fraction by the denominator, or the bottom number of the fraction. How do you change a common fraction to a decimal? The resulting answer will be the value of the fraction expressed as a decimal number.Ģ. The easiest way to convert a fraction to a decimal is to divide the numerator (the top of the fraction) by the denominator (the bottom of the fraction) by using a calculator. What is the easiest way to convert a fraction to a decimal? Reduce the fraction by dividing the numerator and the denominator with the gcd:ġ. Step 3: Simplify (or reduce) the fraction.įind the greatest common divisor (gcd) of the numerator and the denominator: (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.) Step 2: Multiply both top and bottom by 10 for every number after the decimal point. Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number). How to Convert a Decimal to a Fraction with Following Steps It describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. In algebra, a decimal number can be defined as a number whose part and the fractional part is separated by a decimal point.Įxample: 18.65 (eighteen point six five) is a decimal number.Ī fraction represents a part of a whole or, more generally, any number of equal parts. Before you conversions, let’s make sure that you understand what decimals and fractions are:
