简算:0.192×12.5+2.67÷4/5 +1/4 ×3.59

解答:

0.192×12.5 + 2.67÷4/5 + 1/4 ×3.59
=0.192×12.5 + 2.67×1.25 + 3.59×0.25
=1.92×1.25 + 2.67×1.25 + 3.59×0.25
=(1.92 + 2.67)×1.25 + 3.59×0.25
=4.59×1.25 + 3.59×0.25
=4.59 + 4.59×0.25 + 3.59×0.25
=4.59 + (4.59 + 3.59) ×0.25
=4.59 + 8.18 ×0.25
=6.635


怎么把题出错了.从算
0.192×12.5 + 2.67÷4/5 + 5/4 ×3.59
=0.192×12.5 + 2.67×5/4 + 5/4 ×3.59
=0.192×12.5 + 2.67×1.25 + 1.25 ×3.59
=1.92×1.25 + 2.67×1.25 + 1.25 ×3.59
=(1.92 + 2.67 + 3.59)×1.25
= 8.18 ×1.25
= 8×1.25 + 0.1×1.25 + 0.08 ×1.25
= 10 + 0.125 + 0.1
= 10.225
