Compare the parts into which an object is divided with each other. Ratio There is a close relationship between fractions and ratios. The diagram below should help make this link become clear. Fractions Compare the parts into which an object is divided with the whole object. Ratios Compare the parts into which an object is divided with each other. Fraction red = Red:Green = 3:4 Reads as Red to Green equals 3 to 4. The order is important. Green:Red = 4:3 Red:Yellow = Fraction green = 3:5 Yellow:Red = 5:3 Green:Yellow = 4:5 Fraction yellow = 12 parts Yellow:Green = 5:4

Compare the parts into which an object is divided with each other. Ratio Ratios Compare the parts into which an object is divided with each other. State the following ratios for the diagram above. 15 parts Red:Green = 8:3 8 red squares for every 3 green squares. Yellow:White = 3:1 3 yellow squares for every 1 white square. Green:Yellow = 3:3 3 green squares for every 3 yellow squares. White:Red = 1:8 1 white square for every 8 red squares. Red:White = 8:1 8 red squares for every 1 white square.

The Toy Box 16 parts State the following ratios for the toys in the box. Dogs:Teddies = 6:4 6 dogs for every 4 teddies. Clowns:Ducks = 3:2 3 clowns for every 2 ducks. Soldiers:Clowns = 1:3 1 soldier for every 3 clowns. Ducks:Teddies = 2:4 2 ducks for every 4 teddies. Dogs:Clowns = 6 dogs for every 3 clowns. 6:3

The Toy Box 16 parts Ratios can be simplified in the same way as fractions. Divide both sides by the Highest Common Factor (HCF). Dogs:Teddies = 6 dogs for every 4 teddies. 6:4 Dogs:Teddies = 3 dogs for every 2 teddies. 3:2 Equivalently  by 2 A Picture

The Toy Box Ratios can be simplified in the same way as fractions. Divide both sides by the Highest Common Factor (HCF). 20 parts Clowns:Ducks = 9:6 9 clowns for every 6 ducks. Clowns:Ducks = 3 clowns for every 2 ducks. 3:2 Equivalently  by 3 A Picture
