For each 11 mm of coloured fabric Nick uses to make his curtains, he also uses 2 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form

2:11

Step-by-step explanation:

you need to understand the question and then write this.

20:11

2cm=20mm

Therefore the amount of white fabric to the amount of coloured fabric used is 20:11 because the highest common factor of 20 and 11 is 1 so the ratio cannot be simplified further.

i think this is what the question meant but if i interpretated it wrongly u can tell me :)
