3/7 or 13/287, unfortunately no result is returned. The calculation might take a while and does not always return the shortest possible unit fraction sum. Please enter numerator and denominator of a common fraction or the value of a decimal fraction and press the according button.Įxamples: common fraction 5/19 = 1/4 + 1/76 decimal fraction 0.024 = 1/42 + 1/5250 Problem solving and reasoning cards allowing children to solve complex problems in various contexts for unit fractions. A unit fraction sum is only possible for positive values. The famous Rhind papyrus, dated to around. The unit fraction sum gives the fraction as a sum of different unit fractions (and a natural number, if the fraction is larger than 1). A unit fraction is a fraction with numerator 1. A unit fraction has the form 1/n, whereas n is a natural number. 3/4, the according decimal fraction is 0.75. Switch between units, imperial and metric, and find the unit conversion youre looking for.

Hence, every fraction is a number of unit fractions. Unit fractions can be represented on a number line, as shown below. Pupils use knowledge of the relationship between parts and wholes in unit fractions to solve problems. Pupils construct a whole when given one part and the fraction that it represents. Pupils identify when unit fractions cannot be compared. Worksheet 1 Worksheet 2 Worksheet 3 Worksheet 4 Worksheet 5 Worksheet 6. Pupils compare and order unit fractions by looking at the denominator. Below are word problems involving the division of whole numbers by unit fractions, or vice versa. Therefore, you can call them ‘one-fifths’, ‘one-fourths’, and so on. Unit fractions are fractions with 1 as the numerator. For example, create a story context for 4 ÷ (1/5), and use a visual fraction model to show the quotient. Half, third, fourth, or any other number of 1. Interpret division of a whole number by a unit fraction, and compute such quotients. Use the relationship between multiplication and division to explain that (1/3) ÷ 4 = 1/12 because (1/12) × 4 = 1/3. For example, create a story context for (1/3) ÷ 4, and use a visual fraction model to show the quotient.
