G=28+Y -- what the equation translates too
4/7G=2/3Y -- the second sentence
12/21G=14/21Y -- multiplying each side so it is the same denominator
Notice the difference, 28 is 2/21, and 1/21 is 14.
Taking that into account: 14*21=294 294-28 is 266
294*4/7=168, 177+ 1/3. Hmmm.... wrong.. but notice that 168 and 177 +1/3 is relatively close. so the answer is around 294 for Green and 266 for blue. Hope this helps with checking your answer.
