(1)0.125×3/4+1/8×8.25+12.5% (2)(5/12+1 1/6-7/18-4/9×36÷9/19 (3)9999×2222+3333×3334
(1)0.125×3/4+1/8×8.25+12.5%
=0.125×0.75+0.125×8.25+0.125
=0.125×9+0.125
=0.125×10
=1.25
(2)第二个问题实在是看不懂你写的,应该是一个先通分再合并同类项的问题
(3)9999×2222+3333×3334
=9999×2222+3333×3333+3333
=9999×2222+9999×1111+3333
=9999×3333+3333
=10000×3333
=33330000
