数学公式-数学公式÷8=数学公式+数学公式-数学公式+数学公式=0.125×25×32=0.23=

+=0.12+0.98=1.1,12.5%×80=10,-)×12=5,
-÷8=6+-+=0.125×25×32=100,0.23=0.008.

故答案为:,1.1,10,5,6,100,0.008.


分析:本题根据分数与小数的加法,乘法及四则混合运算的运算顺序计算即可.
-)×12可根据乘法分配律计算;
+-+可根据加法交换律计算;
0.125×25×32可将式中的32拆分为8×4后再根据乘法交换律及结合律计算.
点评:完成本题要细心分析式中数据,能简便计算的要简便计算,然后快速准确得出答案.
