网考网解析：
You could solve this by multiplying each quantity and comparing. However, you could also solve by thinking about the quantities in the following ways: 90,531=90,315+216. Therefore, the following is true: 100,315(90,531) =100,315(90,315+216) =100,315(90,315)+100,315(216) Likewise, 100,531=100,315+216. Therefore, the following is true: 100,531(90,315) =(100,315+216)(90,315) =100,315(90,315)+216(90,315) It is apparent that the quantity in Column A is greater than the quantity in Column B. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
