Pg 100 Ex 5d 1,3,5 Find the map ratio of the maps in the following questions 1.2cm on the map represents 1km 2cm : 1km 1km = cm 2 cm : cm 2 : Ans  1 : Drop the units Divide by 2

Pg 100 Ex 5d 1,3,5 Find the map ratio of the maps in the following questions 3. 10km is represented by 10cm on the map 10 cm : 10 km 1km = cm  10km = cm 10 cm : cm Ans  1 : Drop the units

Pg 100 Ex 5d 1,3,5 Find the map ratio of the maps in the following questions 5. ½ cm on the map represents 500 m 0.5 cm : 500 m 1m = 100cm  500 m = 500 x 100 = cm 0.5 cm : cm 5 : Ans  1 : Get rid of point (x 10) -Drop units Divide by 5

Pg 100 Ex 5d 7,9,10 7. The map ratio of a map is 1 : The distance between A and B on the map is 6cm. What is the true distance between A and B MAP : ACTUAL 1 : : ? The true distance between A and B is cm or 3km x

Pg 100 Ex 5d 7,9,10 9. The map ratio of a map is 1 : Find the actual length represented by 2cm MAP : ACTUAL 1 : : ? The actual length is cm or 200m x

Pg 100 Ex 5d 7,9, The map ratio of a map is 1 : Find the distance on the map which represents an actual distance of 36km MAP : ACTUAL 1 : ? : 36 km 36 km = The distance on the map is 1.8 cm x

Any Questions?? You only need to change units the numbers you are comparing have different units New whiteboards! More Practise!

On a map 1cm represents 2km. What distance on the map will represent a real distance of 12 km MAP : ACTUAL 1 cm : 2 km ? : 12 km x 6 6cm

A map has a scale of 1 : How much is a distance of 10cm on the map, in real life? Give your answer in metres! MAP : ACTUAL 1 : : ? x m
