Question

For each 11 mm of coloured fabric June uses to make her curtains, she also uses 1 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form

Answer 1

Answer: The amount of white fabric to coloured fabric as a ratio in its simplest form is
`(10)/(11)`

Explanation:

Given :

Amount of coloured fabric used by June = 11 mm = 1.1 cm (1 mm=0.1 cm)

Amount of white fabric used by June = 1 cm

To find : amount of white fabric to coloured fabric as a ratio in its simplest form

To find the ratio in simplest form , the units of both measurements should be same

Thus
`\frac{\text {amount of white fabric}}{\text {amount of coloured fabric}}=(1cm)/(1.1cm)=(10)/(11)`

The amount of white fabric to coloured fabric as a ratio in its simplest form is
`(10)/(11)`
