What is the sum of the three oddnumbers? 相关知识点: 试题来源: 解析 解:因为乘积的末位数字是3,所以这三个奇数的末位数字中不能有5,那么一定是7,9,1。又因为 60^3=216000300003 , 70^3=343000 , 80^3=512000399993 所以这三个奇数一定是67,69和71,他们的和是67+69+71=207。
The sum of two consecutive odd numbers is 28. What is the smaller odd number? A. 13 B. 15 C. 11 D. 17 相关知识点: 试题来源: 解析 C。设较小的奇数为 x,较大的奇数为 x + 2,它们的和为 28,即 x + (x + 2) = 28,2x + 2 = 28,2x = 26,x = 13。所以较小的奇数是 11。
