答案
解析：这些题目主要考查除法和乘法的运算，包括基础运算和带括号的运算。对于大部分题目，直接计算即可。对于有括号的题目，需要通过除法或乘法找到缺失的数。
答案：
$3500 ÷ 20 = 175$
$1600 ÷ 16 = 100$
$1200 ÷ 60 = 20$
$40 × 180 = 7200$
$108 × 90 = 9720$
$106 × 50 = 5300$
$12 × 800 = 9600$
$906 × 7 = 6342$
$705 ÷ 5 = 141$
$70 × 900 = 63000$
$960 ÷ 48 = 20$
$480 ÷ 96 = 5$
$720 ÷ 36 = 20$
$125 × 8 ÷ 10 = 100$
$25 × 4 ÷ 100 = 1$
$25 × 5 ÷ 5 = 25$
$25 × 4 ÷ 20 = 5$
$250 ÷ ( ) = 50$，所以括号里的数为$250 ÷ 50 = 5$
$12 × ( ) = 36$，所以括号里的数为$36 ÷ 12 = 3$
$240 ÷ ( ) = 24$，所以括号里的数为$240 ÷ 24 = 10$
$350 ÷ ( ) = 7$，所以括号里的数为$350 ÷ 7 = 50$
答案：
$3500 ÷ 20 = 175$
$1600 ÷ 16 = 100$
$1200 ÷ 60 = 20$
$40 × 180 = 7200$
$108 × 90 = 9720$
$106 × 50 = 5300$
$12 × 800 = 9600$
$906 × 7 = 6342$
$705 ÷ 5 = 141$
$70 × 900 = 63000$
$960 ÷ 48 = 20$
$480 ÷ 96 = 5$
$720 ÷ 36 = 20$
$125 × 8 ÷ 10 = 100$
$25 × 4 ÷ 100 = 1$
$25 × 5 ÷ 5 = 25$
$25 × 4 ÷ 20 = 5$
$250 ÷ ( ) = 50$，所以括号里的数为$250 ÷ 50 = 5$
$12 × ( ) = 36$，所以括号里的数为$36 ÷ 12 = 3$
$240 ÷ ( ) = 24$，所以括号里的数为$240 ÷ 24 = 10$
$350 ÷ ( ) = 7$，所以括号里的数为$350 ÷ 7 = 50$
