Answer:
3 days.
Step-by-step explanation:
1 day= 2 1/6
He has 1/2 but we need to change 2 to 6 so x 3 so now times 1 by 3 to 6 3/6
Day 2=4 2/6
And last day 3 3/6
Because in one day they eat 2 whole's so 2 x 3=6 and that has the wholes.
and then 1/6 so 1 x 3=3/6 and 6 wholes so 6 wholes and 3/6 and that means they eat 6 3/6 in 3 day.
Hope it helps have a great day:)
