1 5/12 in decimal form is 1.416 so you take 2 1/2 bags of apples and make it a decimal, is 2.5 so you subtract them and get 1.084 and that in its most simplified feaction is 271/250 and in standard form is 1 21/250 in simplified form so that is how many bags of apple he will have left. Hope this helps!
