(1)纳闷:
为什么这道题回来汇报的人总是说确认62?
Five boxes maximum capacity currently hold pieces
90 70
80 70
50 30
80 50
40 40
rearrange it so that the maximum capacity - holding pieces for all five are the same. So second box should be ?
【讨论】62 My ans:62(SURE)
(2)问两个表达法:
1/3 as many A as B
more than twice A as many as B作者: dongyong 时间: 2002-10-27 22:08
