【答案】2,1.94,0.1,9.8,10,,0.0202,0,0,0,2,0.16,1,
【解析】
试题分析:1.01×0.2×0.1按照从左到右的顺序计算;9﹣9.875先把分数化成小数,再计算;0.1+0.2×0.3先算乘法,再算加法;+÷+先算除法,再算加法;÷3+×先把除法变成乘法,然后运用乘法分配律简算;其它题目根据运算法则直接求解.
解:0.125×16=2, 3﹣1.06=1.94, 0.6÷6=0.1, 16.8﹣7=9.8,
11﹣=10, ﹣=, 1.01×0.2×0.1=0.0202, 0.45×0=0,
0÷125=0, 9﹣9.875=0, 2﹣0=2, 0.1+0.2×0.3=0.16,
+÷+=1, ÷3+×=.
故答案为:2,1.94,0.1,9.8,10,,0.0202,0,0,0,2,0.16,1,.
