Answer:

hiiiiiiiiiiiiiii let's marry

Answer 2

Step-by-step explanation:

If the common factor between blue and green happens to be ‘x’

Then blue happens to be (2x) in number

Green happens to be (5x) in number

As remaining are red and that is also the half of total.

One can easily say that remaining half concluded blue and green.

So sum of blue and green is nothing but number of red balls

Therefore (2x)+(5x) = blue + green = red

Hence, (7x)= red

Therefore, b:g:r::2:5:7

And b:r::2:7
