Document Content and Description Below

A fraction is a portion of a whole that has been divided into equal parts. A common fraction is written as ½. The number 1 represents a whole number called the numerator and the 2 represents a whol... e number called the denominator. Key words: 1) Numerator – the whole number above the fraction line. 2) Denominator – the whole number below the fraction line. Proper Fractions: These are fractions where the numerator is smaller than the denominator, e.g. 1 2 Improper Fractions: These are fractions where the numerator is bigger than the denominator, e.g. 9 2 Mixed Fractions: These consist of a whole number and a proper fraction, e.g. 5 3 4 4 GM 2018 CONVERTING FRACTIONS To convert an improper fraction to a mixed number, simply divide the number by the denominator: Examples: 12 5 = 12 ÷ 5 = 2 r 2 We write this as 2 2 5 . To convert a mixed number to an improper fraction, multiply the whole number by the denominator. Add the numerator to this. Write this answer as the numerator and keep the denominator the same. Examples: 8 1 2 Multiply 8 by 2, and then add 1 This will give you a total of 17 The fraction will therefore be 17 2 EXERCISE 1 Number 1: Convert the mixed numbers to improper fractions: a) 13 2 3 d) 1001 4 15 b) 17 8 11 e) 9 5 7 c) 4 3 9 Number 2: Convert the improper fractions to mixed numbers: a) 41 9 d) 316 3 b) 199 10 e) 1000 125 c) 412 15 [Show More]
