Explanation:
To find out how much one number is larger than another, we subtract the larger one from the smaller number. Therefore:
11/12-5/6;
=11*1/12*1 - 5*2/6*2;
=11/12-10/12;
=1/12;
=0.083.
Thus, the nearest number to 0.083 is 0. So the most accurate estimate of how many pounds of almonds she buys more than pounds of pecans is 0.
