EQUIVALENT FRACTIONS Therefore Multiply x by 2 5
EQUIVALENT FRACTIONS Therefore, Multiply (x) by 2 5 10 9 = 18 Multiplied (x) by 2
EQUIVALENT FRACTIONS 5 11 Multiplied (x) by 7 = 35 77 Therefore, Multiply (x) by 7
EQUIVALENT FRACTIONS 1 4 = Multiplied Divide(X) (÷)by by 33 3 12 Divide (÷) by 3 OR = 9 36 Multiply (x) by 3
SIMPLIFICATION OPTION 1 Divide both the numerator and the denominator by the Highest Common Factor (HCF) or the Greatest Common Factor (GCF) A factor, is a number that divides another number evenly without a remainder. For instance, 3 and 6 are factors of 12 because 12÷ 3 = 4 exactly and 12÷ 6 = 2 exactly. In fact, 1, 2, 3, 4, 6 and 12 are factors of 12
SIMPLIFICATION 24 60 Divide (÷) by HCF: 12 = 3 5 Divide (÷) by HCF: 12
SIMPLIFICATION 125 1000 Divide (÷) by HCF: 125 = 1 8 Divide (÷) by HCF: 125
SIMPLIFICATION OPTION 2 Divide both the numerator and the denominator by 1. Highest Common Factor (HCF) 2. Lowest Common Factor (LCF) – [or any other factor], until you can't go any further (try dividing using the prime numbers: 2, 3, 5, 7, 11. . . etc), therefore use the Lowest Common Prime Number (LCPN). Example on next slide:
SIMPLIFICATION Divide (÷) by LCPN: 2 24 60 = 12 30 = Divide (÷) by LCPN: 2 6 15 = 3 5
SIMPLIFICATION Divide (÷) by LCPN: 5 125 1000 = 25 200 = Divide (÷) by LCPN: 5 5 40 = 1 8
