1樓:空夜的星
1.25*8*1.1=10*1.1=11
2樓:長瀨綿秋
(1)7/8÷3/4+7/8x2/3
=7/8x4/3+7/8x2/3
=7/8x(4/3+2/3)
=7/8x2
=7/4
(2)0.45×1/6÷0.45x1/6
=(0.45÷0.45)x(1/6x1/6)=1x1/36
=1/36
(3)4.8÷5/13-4又4/5x1.6=4.8x13/5-4.8x8/5
=4.8x(13/5-8/5)
=4.8x1
=4.8
8.88乘以1.25的簡便計算(遞等式)
3樓:快樂無限
8.88x1.25
=(8+0.8+0.08)x1.25
=8x1.25+0.8x1.25+0.08x1.25=10+1+0.1
=11.1
希望能幫到你!

8.88乘以1.25的簡便計算(遞等式)
8.88*1.25
=1.11*8*1.25
=1.11*10
=11.1
5樓:匿名使用者
=(8+0.8+0.08)×1.25
=8×1.25+0.8×1.25+0.08×1.25=10+1+0.1
=11.1
加油吖!
