A FRACTION is anumber thatrepresents a part ofa whole. 1 Whole Cake 4 equal cut pieces of cake equals 1 whole cake. Those parts of the cakes are a FRA CTION of the cake. Home
4.
Numerator The number on the top is called the numerator It represents the part of the whole number The shaded part Numerator 1 is the numerator Whole number 2 These 2 equal parts make the whole Numerator 2 Whole number 6 NextHome
5.
Denominator The number on the bottom is called the denominator It represents the whole numberPart of the whole 1 Denominator 2 These 2 equal parts make the DENOMINATOR Numerator 2 Denominator 5 Home
6.
Adding Fractions with common denominator Is as simple as adding the 2 top numbers (numerators) together 3 6 9 + = 10 10 10
7.
Adding Fractions with different denominators Fractions with different denominators need to be made READY first before they can be added together To get them READY you must find the common denominator COMMON DENOMINATOR can be found by finding the lowest common mulitple (LCM) of the two denominators
8.
Finding the lowest common multiple The lowest common multiple of two numbers is the lowest number in Both lists of multiples or the lowest number both can be divided by Multiples of 3 are 3,6,9,12,15,18....... Multiples of 4 are 4,8,12,16,20,24.... 1 1 . So the lowest common multiple is 12 + 3 4
9.
You cant add fractions1/3 + 1/4 With different denominators Turn both fractions into twelfths For 3 to become a 12th you need to multiply it by 4 And for 4 to become a 12th you need to multiply it by 31 4 4 1 3 3 x = x =3 4 12 4 3 12
10.
Completing the Addition 1/3 = 4/12 AND ¼ = 3/124 3 7 + =12 12 12
