For each 24 mm of coloured fabric Gordon uses to make his curtains, he also uses 1.2 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form.

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

Ratio

12 / 24

1 / 2

1 : 2

So, ratio of the amount of white fabric to coloured fabric is 1 : 2
