Answer:
1 : 2
Step-by-step explanation:
Given that,
amount of coloured fabric Gordon use to make his curtain = 24mm
amount of white fabric Gordon use to make his curtain = 1.2cm
To find,
ratio of the amount of white fabric to coloured fabric
1 cm = 10mm
1.2 cm = 1.2 * 10
= 12 mm
12 / 24
1 / 2
1 : 2
So, ratio of the amount of white fabric to coloured fabric is 1 : 2
