Think of it this way. 1/5= 20%, 1/4=25% and 1/3= 33% (about)
Also, if the grandpa got the same amount as the second child, that would mean between the two, they consumed 50% of the ice cream. Add the 20%, then subtract that result from 100% to get the percent the oldest got and convert it to fraction form.
Grandpa Mick opened a pint of ice crew. He gave his youngest grandchild 1/5 of the ice cream and his middle grandchild 1/4 of the remaining ice cream. Then, he gave his oldest grandchild 1/3 of the ice cream that was left after serving the others. Who got the most ice cream?
What fraction of the pint of ice cream will be left if grandpa mick serves himself the same amount as the second grandchild?

oldest grandchild
1 pint of ice cream = 100%
minus 1/5 or 20% - 20 = 80%
minus 1/4 or the REMAINING
80% not the original whole
pint 80-1/4 = 60
(20)
The REMAINING 60% is
divided 3 ways 60/3=20
everyone gets the same!
