Proportion: Inverse proportion (x and y) Silent Teacher Intelligent Practice Narration Your Turn When y = 5, x = 12 Find y when x = 6 When y = 10, x = 12 Find y when x = 6 Example For more videos visit mrbartonmaths.com/videos

Worked Example Your Turn y is inversely proportional to x When y = 6, x = 10 Find y when x = 4 y is inversely proportional to x When y = 6, x = 20 Find y when x = 4 @mrbartonmaths

y is inversely proportional to x… When y = 12, x = 5 Find y when x = 3 When y = 5, x = 12 Find y when x = 6 When y = 10, x = 12 When y = 10, x = 24 When y = 20, x = 24 Find y when x = 12 When y = 10, x = 12 Find y when x = 6 Find x when y = 6 When y = 30, x = 36 Find x when y = 54 When x = 15, y = 18 When x = 1.5, y = 18 @mrbartonmaths

y is inversely proportional to x… When y = 12, x = 5 Find y when x = 3 When y = 5, x = 12 Find y when x = 6 When y = 10, x = 12 When y = 10, x = 24 When y = 20, x = 24 Find y when x = 12 When y = 10, x = 12 Find y when x = 6 Find x when y = 6 When y = 30, x = 36 Find x when y = 54 When x = 15, y = 18 When x = 1.5, y = 18 y = 20 y = 20 x = 20 y = 20 x = 180 y = 10 x = 20 y = 20 x = 5 y = 40 x = 0.5 y = 40 @mrbartonmaths
