Liam had 75% more magnets than John at first. Liam gave away 200% as many magnets as John. John was left with 25% of the magnets he had at first. What fraction of Liam's magnets did he have in the end?
L = 1.75 J This is given
Then J gives away 'g'
J - g = .25 J
.75J = g
Liam gave away 200% or 2 g which is 1.5J
L = 1.75J originally then subtract 1.5J
Lnew = .25J
so the fraction Liam has at the end is .25J / 1.75J = 1/7
