Question

The ratio of the width

to the length of the
Canadian flag is 1:2.
a) The flag on the cover of an atlas is 12 cm wide. How long is it?
b) A large flag outside a Calgary school is 3 m long. What is its width?

Answer 1

Answer to a: the cover is 24 cm long.

Step-by-step explanation:
Since the ratio is 1:2 and the width is 1 in the original ratio, you take 12•2 to get the width.

Answer to b: the width is 150 cm or 1.5 meters

Explanation: 1 meter is equivalent to a hundred centimeters so you multiply that by three and get 300 cm for the length, then divide that by two and get 150 cm or 1.5 meters
