口奥五1.计算:98，998，9998，99998=2.甲、乙两名运动员在环行跑道上从同一地点同时背向而跑，已知甲运动员跑一圈要 80分钟。
如果在出发后 30分钟两人第一次相遇。
问:乙运动员跑一圈要多少分钟, 3.如图:一个长方形被分成 4个不同的三角形，如果绿色三角形的面积是原长方形面积的15，黄色三角形面积是 15平方厘米，那么原长方形的面积是多少平方厘米,黑4.在4×4的方格棋盘中，取出一个由三个小方格组成“L”型(右上图)，共有种不同的取法,答案(1)111092;(2)甲的速度是乙的速度:30?(80,30)=0.6倍乙跑一圈:80×0.6=48(分钟)(3)15?(0.5,0.2)=50(平方厘米)(4)解:在2×2的正方形中,有 4种取法。
4×4的方格棋盘中共有 3 ×3=9个2×2的正方形。
所以不同的取法共有:3×3×4=36(种)口奥六1.计算:3.6×31.4，(31.4，12.5)×6.4=2. A、B、C、D四个数，每次去掉一个数，将其余的三个数求平均数，这样计算了 4次，得到以下四个数:13、16、20、23问:(1)A、B、C、D四个数的平均数是多少,(2)A、B、C、D中最大的数是几,3.一个长方体，它的高和宽都相等，如果把它的长去掉 3厘米，就成为表面积是 150平方厘米的正方体，原来长方体的体积是多少平方厘米,。
4. 12345678910111213…19981999除以 9的余数是答案:(1)原式=394;(2)解:平均数:(13，16，20，23)?4=18最大数:18×4,13×3=33(3)解:正方体一个面的面积:150?6=25(平方厘米)因为25=5×5，所以正方体棱长是 5厘米。
长方体体积:5×5×(5，3)=200(平方厘米)(4)1。
因为所求余数与前 1999个自然数之和除以 9的余数相同。
口奥七1.计算:17.48×37,174.8×1.9，1.748×820=2.双休日,学生们到郊外去玩。
甲买了 5只面包，乙买了同样的面包4只，当午餐用。
不料丙也参加午餐，但没有买面包，三人就均分着吃。
丙按买价拿出钱来，他给甲 1元 5角，给乙1元 2角。
3.长方体的表面积是 74平方厘米，其中一个底面的面积是 10平方问:他这样算对不对，为什么,厘米，底面的周长是 9厘米。
这个长方体的体积是多少立方厘米, 4.甲数除以乙数，乙数除以丙数，商相等，余数都是 2。
甲、乙两数之和是 478，那么甲、乙、丙三数之和是多少,(1)原式=1748; 答案:(2)单价:(12，15)×3?(5，4)=9(角)应给甲:9×5,(15，12)=18(角)=1元 8角应给乙:(15，12),18=9(角) 所以，丙算得不对，应给甲 1元 8角，给乙 9 角。
(3)侧面积:74,10×2=54(平方厘米)高:54?9=6(厘米)长方体体积:10×6=60(立方厘米)(4)714或 517或 489。
乙数应是 478,2=476的约数。
经验算，甲、乙、丙三数可以是 240、238、236或 359、119、39或410、68、11。

当弟弟跑到 95米处时，哥哥追上了弟弟。
剩下的 5米，哥哥比弟弟先跑完。
