如图： 由数轴得：-4＜-2＜0＜2＜3．

解答：解：如图：故-|-3|＜-53＜-0.25＜0＜2.5＜（-2）2．

在数轴上表示出来如图所示：∴-4.5＜-|-3|＜-|-2.5|＜（-1）99＜0＜2．,4,画一条数轴，在数轴上把下列各数表示出来，并用“＜”连接各数．-|-2.5|，-4.5，2，0，（-1） 99，-|-3|

-（-2）=2，-0.5，0，-|-4|=-4，在数轴上表示为：，用“＜”把它们连接起来为：-4＜-0.5＜0＜2．

解：数轴如图所示： 根据数轴，右边的数大于左边的数：﹣2 2 ＜﹣3 ＜﹣ ＜0＜|﹣2.5|＜﹣（﹣4）．

画一条数轴,在数轴上表示下列有理数,然后把它们用“<”号连接起来:

画出数轴并表示有理数1.5-22-2.5如下：首先，我们需要画出数轴，然后标出各个有理数的位置。o|---＞-2.52||-21.5||o2.5，然后，将各个有理数标在数轴上：1.5o-2|||-2.5＜---＜---2|||-2＜---

（1）答案如图：（2）-5/2＜0＜2.5＜3.5＜5 （3）由于-5/2换算成小数就是-2.5，所以其相反数就是2.5。

解：数轴如图所示： 根据数轴，右边的数大于左边的数：﹣2 2 ＜﹣3 ＜﹣ ＜0＜|﹣2.5|＜﹣（﹣4）．

解答：解：如图：故-|-3|＜-53＜-0.25＜0＜2.5＜（-2）2．

画一条数轴,把给出的有理数在数轴上表示出来,并用“<”连接.-0.25,2.5,0,-53,(-2)2,-|-3|.

-2.5,-2,-3/4,0,1.5,2,9/2按照这个顺序标到数轴上就行了

1.5可以在数轴1、2的中间。-2在0左边的2个单位。2在0右边的2个单位。-2.5在-2和-3的中间。9/2=4.5在4、5的中间。-3/4没有满-1，在0和-1之间平分4等分选三分就是-3/4。数轴 为一种特定几何图形。直线

数轴的作用：1、数轴能形象地表示数，横向数轴上的点和实数成一一对应，即每一个实数都可以用数轴上的一个点来表示。2、比较实数大小，以0为中心，右边的数比左边的数大。3、虚数也可以用垂直于横向数轴且同一原点的纵向

画出数轴并表示下列有理数:1.5,负2.5,负2.5,2分之9,负4分之3,0

以0为原点，作一条以右方向为正方向的数轴，各点的位置如图：

-2.5,-2,-3/4,0,1.5,2,9/2按照这个顺序标到数轴上就行了

在数轴上我们通常以有理数0为原点O 左边为负数；0左边一个单位长度为-1 相应的右边一个单位长度为1 -2.5<-2<-2/3<0<1.5<2<9/2

画出数轴并表示有理数1.5-22-2.5如下：首先，我们需要画出数轴，然后标出各个有理数的位置。o|---＞-2.52||-21.5||o2.5，然后，将各个有理数标在数轴上：1.5o-2|||-2.5＜---＜---2|||-2＜---

画出数轴并表示有理数1.5 -2 2 -2.5

我承认是很粗糙的
如图：A：2/9，B：0，C：1.5，D：-2/3，E：-2，F：-2.5
-22＜-2.5＜-|-2|＜0＜-（-3）．
如图：故-|-3|＜- 5 3 ＜-0.25＜0＜2.5＜（-2） 2 ．
规定了原点、方向和刻度单位的线段就表示数轴。数轴上每一个点都表示一个实数。把有理数表示的点距离原点的距离表示出来，点就表述出来了。
folklore from ancient myth, that humans yang fire is light, go Heilu if people call your name, you have a look around it was a ghost blew out the light, move the soul. The same name novel Tomb and the world adventures. Jiangning Zhenning Nishimura is on the peak location very remote areas, local topography is hilly, economically backward, the villagers mostly living by tea. In April, the peak of the police station on Jiangning here to visit in when some villagers to the police reflect a strange situation. Tea Lane has also been a lot of people dug pit, they will not come to steal our tea,air max 95, right? 4 月 spring when the market is, the villagers said that many of these unidentified tea is bad for people who dig their great loss, request the police to seize the bad guys. Police find it strange that tea was also stolen? So the villagers to lead the way to the tea houses called view. Live in a place the locals called the broad mountain,griffeys women, on the hillside tea fields, police found a lot of really strange pit,nike air max TN, each pit is 1.5 meters to 2 meters wide,Lebron James Shoes VIII, different shades,griffey shoes 2011, a light meter deep, deep then four or five meters. the police carefully observed, next to the soil in these holes there are some scattered fragments of porcelain, and in some pit exposed brick interior also faint. this remote little village will be the tomb? If so, the tomb is who? Tomb guess so that people understand, the police do not have the professional archaeological knowledge, in order to identify the situation, police contacted the Nanjing Museum archaeologists came to the scene. archaeologists found after careful investigation, from the left at the scene of the porcelain pieces, pottery, Muzhuan other things to determine,womens air max TN, garden ground should be a family of Eastern Han Dynasty tombs, the tomb is at least as archaeologists said the pit is likely that thieves recently dug Dao Dong,asics onitsuka tiger, from the field of view, thieves should not succeed, will definitely come back recently. experts also said that from the field situation, these thieves is not really an Said to be police decided by a secret way to catch thieves squat. Police Station every day to send someone to conduct the survey found Daodong place, but thieves seem to be cautious and never appeared. Some time ago, the police patrol found a new tea and there were two pits, two pits dug especially deep,Asics Mexico 66, the human eye can already see the holes in the soil in large Muzhuan. Police continue to ambush around in tea, has been defensive from 20:00 to 23:00 and more, seven out of the shadows really channeling. seven individuals carrying the shovels and other tools, the two went straight to a new pit dug next to prepare Two thieves got into the pit until after several police suddenly shouted, as the higher number of thieves, police worry that outnumbered the rest of the police on the ground to stay in the thieves throw stones. idea of ??being killed a few people who were spooked this posture, tool in the hands dropped quickly fled. Two of them were pushed to the Dao Dong in a police,nike air max LTD II, and another one ran out and ran a few steps back and then faint, just fall into police hands. Originally,nike air griffey, the police threw a stone, he thought it was the police in front of the block, so they ran back. 7 个 grave robbers, the police arrested the five, there are two temporary escape, the police are out hunting. Interestingly,purple griffeys, these thieves arrested after the vehicle due to a moment did not bring them to the police station, police focused on the five thieves to dig their own Dao Dong, the other police cars came. Upon review, this gang of thieves are Zhenjiang Jurong people, and live in the same district,air max LTD, led to Panmou, their long-term flows Jiangning, Baoying, Jurong, etc. Tomb has had more than one excavation of ancient tombs. Dug some bronze mirrors, porcelain, pottery and other objects, all at low prices shot up. Panmou admitted that they Also dug up some pots and pans before the order price, we sold a few hundred dollars, and some buyers to get a red Nanjing cigarettes changed, According to his account of the police in his home in Jurong, Tomb elements active in a group,凶犯劫财杀人后潜逃18年被抓 Lebron James Shoes sale, they are proficient in feng shui, superb craftsmanship, where a tomb, to see the terrain can be seen.
