Question 3 Fill in the missing numbers for these ratios that are proportional to 18 : 24. 3 : ______  12 : ______ 20 : ______ 27 : ______We can write this as πŸπŸ–/πŸπŸ’ = πŸ‘/"βŽ•" 18 Γ— "βŽ•" = 3 Γ— 24 "βŽ•" = (3 Γ— 24)/18 "βŽ•" = (3 Γ— 4)/3 "βŽ•" = 4 So, ratio is 3 : 4 πŸπŸ–/πŸπŸ’ = 𝟏𝟐/"βŽ•" 18 Γ— "βŽ•" = 12 Γ— 24 "βŽ•" = (12 Γ— 24)/18 "βŽ•" = (12 Γ— 4)/3 "βŽ•" = 4 Γ— 4 "βŽ•" = 16 So, ratio is 12 : 16 Also, πŸπŸ–/πŸπŸ’ = 𝟐𝟎/"βŽ•" 18 Γ— "βŽ•" = 20 Γ— 24 "βŽ•" = (20 Γ— 24)/18 "βŽ•" = (20 Γ— 4)/3 "βŽ•" = 26.66… So, ratio is 20 : 26.66.. This is not multiplied properly Maybe the book meant 21 Then, ratio is 21 : 28 πŸπŸ–/πŸπŸ’ = πŸπŸ•/"βŽ•" 18 Γ— "βŽ•" = 27 Γ— 24 "βŽ•" = (27 Γ— 24)/18 "βŽ•" = (27 Γ— 4)/3 "βŽ•" = 9 Γ— 4 "βŽ•" = 36 So, ratio is 27 : 36
