2019年小学六年级下册数学解比例题班级_姓名_一、填空题。1判断两个比能不能组成比例，要看（ ）。218：624：（ ）（ ）3（ ）%。3甲数是乙数的1.5倍，用最简单的整数比表示（ ）：（ ）。4在一个比例中，两个内项的积是最小的合数，一个外项是，另一个外项是（ ）。5在一个比例里，两个外项互为倒数，其中一个内项是4.5，另一个内项是（ ）。6在一个比例中，两个外项的积是最大的两位数，其中一个内项是33，另一个内项是（ ）。7在比例3：126：24中，如果将第一个比的后项加6，第二个比的前项应（ ），比例才能成立。8在比例尺是1：xx000的地图上，量得甲地到乙地的距离是7厘米，实际距离是（ ）千米。二、判断题。1两个比可以组成一个比例。（ ）2任意两圆各自的周长和直径的比才都可以组成比例。（ ）3在一张地图上，4厘米表示实际距离200米，这幅地图的比例尺是1：50。（ ）4x：167：6，求x的值叫做解比例。（ ）5在比例里，两个外项的积与两个内项积的差是0。（ ）6在比例尺是8：1的图纸上，2厘米的红段表示零件实际长16厘米。（ ）三、计算题。1解比例。2依照条件列比例，再解比例。（1）最小的质数与最大的一位数的比等于与x的比。（2）最小的两位数与最大的两位数的比等于3与x的比。（3）最小的质数与最小的合数的比等于分子是1的最大真分数与x的比。四、应用题。1在比例尺是1：6000000的中国地图上，量得上海到南京的铁路长是5厘米，一列火车从南京开往上海用了8小时，求火车的速度。2一个轴承图的比例尺是4：1，如果在图上量行长是34厘米，实际长是多少？3一列火车以每小时70千米的速度从北京开往韶山，20小时后到达，在地图上量得两地间的距离为35厘米，请你算算这幅地图的比例就。参考答案一、填空题。1它们的比值是不是相等。2 8930033：2637减28140二、判断题。1错误2正确3错误4正确5正确6错误三、计算题。2 (2)10:99=3:x x29.7 x=1四、应用题。1解：设南京到上海的实际距离为x厘米，x3000000030000000厘米30千米，300837.5千米/小时2解：设实际长度为x厘米， x=8.5370201400千米，1400千米140000000厘米，35：1400000001：4000000附送：2019年小学六年级下册期中英语水平测试题 (I)一.选择最合适的答案。（10%）（ ）1.Sarah is sick.
