For each 48 mm of coloured fabric Fiona uses to make her curtains, she also uses 1.2 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form.​

1:4

Step-by-step explanation:

Convert the units  

The conversion is as below :

1 cm = 10 mm

Convert the 1.2 cm measurement to mm.

1.2 × 10 = 12 cm

Colored fabric = 48 mm

White fabric = 12 mm

The ratio of the amount of white fabric to colored fabric is :

12/48 = 1/4

The ratio is therefore 1 : 4

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

1.m=2

2.m=-6

3.m=3

4.m=1/2
