He gives twice 69 potatoes to Tom, which is 69*2 = <<69*2=138>>138 potatoes
He gives one-third of 138 potatoes to Anne, which is 138*(1/3) = <<138*(1/3)=46>>46 potatoes
In total, he has given out 69+138+46 = <<69+138+46=253>>253 potatoes
He initially had 300 potatoes so he now has 300-253 = <<300-253=47>>47 potatoes left
