A seamstress has three colors of ribbon: red is 126 cm, blue is 196 cm, and green is 378 cm long. She wants to cut them 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 :

Answer:

14cm is the greatest length

Step-by-step 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! :)
