Question:

This sketch shows the dimensions of a room. Draw a scale diagram of the room with a scale of 1 : 150.

1 : 150 means that the lengths on the diagram must be 150 times smaller than those of the actual room. We need to divide by 150.
9 m = 900 cm so the diagram length is 900 cm ÷ 150 = 6 cm.
6 m = 600 cm so the diagram length is 600 cm ÷ 150 = 4 cm.
The scale drawing is as shown.
