Kelvin collected some local and foreign stamps. 2/3 of them were local stamps and the rest
were foreign stamps. After he gave away 5/6 of his local stamps and 125 foreign stamps, he
had 1/6 of his stamps left.
(a) How many stamps did Kelvin give away?
(b) What fraction of his stamps given away were local stamps?

fix or eschew the NLP routines!

If he started with x stamps, then he gave away
(5/6)*(2/3)x + 125 = (5/9)x + 125 stamps
that means
4/9 x - 125 = 1/6 x
x = 450
(a) 5/9 * 450 + 125 = 375
(b) 250/375 = 2/3

Although I see competent tutors here who were on Jiska (eg oobleck, mathhelper) the new automatic answer system seems to be a total disaster for the math, physics and chemistry questions that I am accustomed to helping with. More often than not the answers are incorrect but even if correct they are so brief that I can not imagine them being of any use to the student unless a cheater taking a test. This is just insane.

(a) Kelvin gave away 5/6 of his local stamps and 125 foreign stamps, so he gave away a total of (5/6)*(2/3)*(total number of stamps) + 125 = (10/9)*(total number of stamps) + 125 stamps.

(b) Kelvin gave away 5/6 of his local stamps, so the fraction of his stamps given away that were local stamps is 5/6.
