Question

For each 8 mm of coloured fabric Peter uses to make his curtains, he also uses 1.5 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form.

Answer 1

First convert 8 mm to cm.

We know that 8 mm = 0.8 cm.

White fabric to coloured fabric =

1.5 to 0.8

1.5/0.8

This can be expressed as 15/8 or as a mixed number in the form 1_(7/8).
