第十讲 数字谜综合练习

  1. 答案:736.解答:由三个加数的个位之和是14,十位之和是12,百位之和是11,可知第二个加数最大,大小为736

  2. 答案:57.解答:每一列最多能进两次位,一共最多进6次位,所以三个加数的数字之和最大是 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,如 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>

  3. 答案:10504.解答:要使乘积最小,第四行最好是 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> 的形式,容易推断出乘积最小的乘法算式是 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>

  4. 1)答案: <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> .解答:全部填加号的话,和应该是 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,因而只要把总和是 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> 的数前面的加号改为减号即可.
    2)答案: <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> .解答:比较两边质因数23567的个数即可判断填乘号还是除号.

  5. 答案:6.6.解答:算式结果要最小,其中的两个小数的整数部分应尽量小,且分数的分母尽量大,即 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> 的形式,它写成分数变成 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,最小是 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>

  6. 答案:36.解答:考虑到乘积的尾数是6,因而这三个连续自然数的个位数字只能是123678.再通过大小估计: <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,所以三个自然数只能是111213,和是36

  7. 答案:198.解答:由大小估计,可推断出这个自然数是三位数,设为 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,则 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,化简得: <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>  <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>  <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>  <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> 均是不超过9的自然数),所以 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>  <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>  <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,所求的自然数是198

  8. 答案:14.解答:每行的数以三个方格为一个周期:253253,每列的数也以三个方格为一个周期:15141514.所以★所在方格应填14

  9. Shape1 案:17.解答:如右图 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a> ,所以 <a href="/tags/48/" title="练习" class="c1" target="_blank">练习</a> <a href="/tags/226/" title="数字" class="c1" target="_blank">数字</a> <a href="/tags/279/" title="综合" class="c1" target="_blank">综合</a> <a href="/tags/545/" title="字谜" class="c1" target="_blank">字谜</a>
