44、颗,即 12+12=24(颗),24 能被班级人数整除,又 24 能分解为24=124=2 12=3 8=46 由班级人数大于12,可知符合题意的是24 人.所以,共有弹子数 1224-12=276(颗).12.用试除的方法可知:199119911991可以被 13 除尽.原数 a 有 1991 个 1991.因为 1991除以 3 余 2,所以 a 与 19911991除以 13 所得余数相同.又 19911991除以 13 余 8,所以 a 除以 13的余数也是 8.13.因为 777777 13=59829,即 777777 能被 13 整除,把这 100个 7,从第一个起,每 6 个分
45、成一组,1006=164，共 16 组还多 4 个.每一组除以 13 的商都是 59829,7777除以 13的商是 598,余数是 3.所以,100个 7 组成一百位数除以13 后,余数是 3,商数中各位数字之和是(5+9+8+2+9)16+(5+9+8)=550 14.设甲所得的商和余数分别为a 和 b,乙所得的商和余数分别为c 和 d,于是由题意知8a+b=9c+d,a+d=13.将 d=13-a 代入前一式并整理后即得9(a-c)=13-b上式左端是 9 的倍数,因此 13-b 也是 9 的倍数.由于 b 是被 8 除的余数,所以 b 介于 0 与 7之间.故 b=4.答 案答案:1.
46、15,21,35 从 107里减去余数 2,得 107-2=105,所以 105 是除数与商数相乘之积,将 105分解质因数得105=3 57,可知这样的两位数有15,21,35.2.5 根据带余数除法中各部分之间的关系可知，商除数=27-3=24.这样可通过分解质因数解答.文档编码:CR7O5R9O7D1 HZ7F6G5I4B7 ZC2R8Y4A10F3文档编码:CR7O5R9O7D1 HZ7F6G5I4B7 ZC2R8Y4A10F3文档编码:CR7O5R9O7D1 HZ7F6G5I4B7 ZC2R8Y4A10F3文档编码:CR7O5R9O7D1 HZ7F6G5I4B7 ZC2R8Y4A10
