The length of a road is 96m, we plan to plant trees on both sides of the road. And we plan to plant trees every 4 m on the road. But we find that the distance is too close after we draw the signs. So we plant the trees every 6m on the road. How many signs neednt to be marked?6. 在一条长96米的路两侧，计划每隔4米栽一棵树，画好“记号”后发现距离过近，改为每隔6米栽一棵树，不要重新做的“记号”有多少个？（两段无需做“记号” ）7. The length of a rope is 180cm, we mark it from the beginning every 3cm and every 4cm. And then we cut it at the points that there are no marks. How many sections can we cut?7. 有一根180厘米长的绳子，从一端开始每隔3厘米做一个记号，每隔4厘米也做一个记号，然后沿有记号的地方剪断。绳子共被剪成了多少段？8. A kindergarten borrows some books from a library. If the kindergarten borrows 35 books and the teacher divides the books equally to his children, there is 1 book lacked. If the kindergarten borrows 56 books and the teacher divides the books equally to his children, there are 2 books spared. If the kindergarten borrows 69 books and the teacher divides the books equally to his children, there are 3 books lacked. How many children at most are there in the class?8. 某幼儿园借阅图书，如借35本，平均分给每个小朋友差1本；如借56本，平均分给每个小朋友后还剩2本；如果借69本，平均分给每个小朋友则差3本。这个班的小朋友最多有多少人？9.
