Question

A seamstress has three colours of ribbon; the red is 126cm, the blue is 196cm and the green

is 378cm long. She wants to cut them up so they are all the same length, with no ribbon
wasted. What is the greatest length, in cm, that she can make the ribbons?

Answer 1

14cm is the greatest length

Explanation:

Hi!

So the question is basically asking for the greatest common factor between each of these numbers (if I understood the question right so here we go) :

The GCF in this case is 14:

126 / 14 = 9

196 / 14 = 14

378 / 14 = 27

Please feel free to ask me any more questions that you may have!

and Have a great day! :)
