Can you… If not you need Find parts of a ratio
Share an amount in a ratio Try a test If not you need TOP: Review simple ratios Practice 1: Cancelling ratios and finding missing parts Practice 2: Sharing an amount in a given ratio TAIL

TOP: Solve these simple ratio questions
Bob has 7 pens and Sarah has 14 pens. Write this as a ratio in its simplest terms. Joanne has 12 kittens and Louie has 3 kittens. Write this as a ratio in its simplest terms. Write these ratios in their lowest terms: (a) 5 : 35 (b) 28 : 14 (c) 18 : 36 : 42 (d) 40cm : 1m Lesson

Practice 1: Cancel the following ratios into their lowest terms:
15 : 20 35 : 40 10 : 35 8 : 24 120 : 150 Using the given ratio, find the missing part in the second ratio in each question. 3 : 4 (7) 3 : 7 (8) z : 5 x : : y 15 : 20 12 : 15 (10) 8 : 4 (11) 2 : 5 a : : b 9 : c Lesson
