简便计算:7250÷25×4.4×25

7250÷25×4.4×25
=7250×4.4×25÷25
=7250×4.4
=31900

7250÷25×4.4×25
=7250×(1/25)×(44/10)×25
=7250×(44/10)×(1/25)×25
=725×(40+4)
=725×40+725×4
=29000+2900
=31900

7250÷25×4.4×25=7250×(4+0.4)=29000+2900=31900

7250÷25×4.4×25
=7250×4.4
=7250×4×1.1
=29000×1.1
=31900

先算7250除以25 再算4.4乘以25 然后两个结果相乘

7250÷25*4.4*25=7250*4.4*(25÷25)=7250*4.4=7250*4*1.1=31900

7250×4.4×25除以25
=7250×4.4
=(290×25)×(4×1.1)
=290×(25×4)×1.1
=290×100×1.1
=31900
我先回答的~

7250÷25×4.4×25=7250÷25×25×4.4=7250×4.4=7250×(4+0.4)=29000+2900=31900
