Order four-thirds, four-sevenths and four-fifths from least to greatest.Home / math / fraction calculator Fraction Calculatorīelow are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Who jogged the greatest distance? (Enter the name) Maria jogged for two-fifths of a mile, Laura jogged for one-fourth of a mile, and Sasha jogged for three-tenths of a mile. Which of these baked items had the shortest baking time? Which is the greatest?Ī chef takes three-fourths of an hour to bake a pie, two-thirds of an hour to bake cookies, and five-sixths of an hour to bake muffins. Order two-thirds, eight-thirds and five-thirds from least to greatest. Order four-sevenths, two-sevenths and five-sevenths from least to greatest. Note: To write the fraction two-thirds, enter 2/3 into the form. After you click ENTER, a message will appear in the RESULTS BOX to indicate whether your answer is correct or incorrect. In Exercises 1 through 5, click once in an ANSWER BOX and type in your answer then click ENTER. It is helpful to write a number in a circle next to each fraction to compare them more easily. Summary: When ordering three or more fractions from least to greatest, compare two fractions at a time. The fraction with the smaller denominator is the larger fraction. The larger fraction is the one with the greater numerator.Ĭompare two fractions at a time. The larger fraction is the one with the greater numerator.Ĭonvert each fraction to an equivalent fraction with a common denominator.
R U L E S F O R O R D E R I N G F R A C T I O N SĬompare two fractions at a time. Let's try to summarize what we have learned. Since the number of common multiples of any two whole numbers is endless, there are many possible solutions to this problem. We could have also chosen larger common multiples of 2 and 4, such as 16, 24, 32, and so on. This allowed us to name a fraction between two-eighths and four-eighths, resulting in three-eighths as our answer. Instead, we chose eighths as our common denominator. If we had, then it would be difficult to name a fraction between one-fourth and two-fourths. Let's look at another example.Ĭonvert these fractions to equivalent fractions with a common denominator. To order fractions with like numerators, look at the denominators and compare them two at a time. You can see that as the denominator gets larger, the fraction gets smaller. These fractions are unit fractions: Each of them has the same numerator. If you need a visual representation of example 5, look at the shaded rectangles below. Since these fractions have like numerators, we will compare the denominators two at a time. Order these distances from least to greatest. It is helpful to write a number in a circle next to each fraction to compare them more easily. Let's look at another example.Įxample 5: Ned jogged for one-third of an mile, Moze jogged for one-half of a mile, and Cookie jogged for one-fifth of a mile. To order fractions with unlike denominators, use the LCD to write them as equivalent fractions with like denominators. Solution: Ordering the time spent on Jack's homework from least to greatest, we get: Math, Science and Reading. We will use the least common denominator (LCD) to write these fractions as equivalents fractions with like denominators, and then compare them two at a time. Order the time spent to complete Jack's homework by subject from least to greatest.Īnalysis: These fractions have unlike denominators. Let's look at another example of ordering fractions with like denominators.Įxample 3: It takes Jack three-fifths of an hour to complete his math homework, five-sixths of an hour to complete his reading homework, and two-thirds of an hour to complete his science homework. To order fractions with like denominators, look at the numerators and compare them two at a time. We were able to order these fractions from least to greatest because they have like denominators. Solution: Angie drank the smallest part of the cup. What part of the cup did each child drink? Who drank the smallest part of the cup? Who drank the largest part of the cup? Who fell in the middle?Īnalysis: Write the part of the cup that each child drank as a fraction, and then order them from least to greatest. Her sister Angie drank 3 ounces, and her brother Mark drank 5 ounces.
Example 1: An 8-ounce cup of milk was served to each of three children.
