1樓:八戒你胖咯
4.8x3.1十6.2x7.6
=2.4x2x3.1十6.2x7.6
=(2.4+7.6)x6.2
=10x6.2=62
2樓:快樂無限
4.8x3.1十6.2x7.6
=4.8x3.1十(3.1x2)x7.6
=4.8x3.1十3.1x15.2
=3.1x(4.8+15.2)
=3.1x10x2
=62希望能幫到你!
3樓:匿名使用者
4.8*3.1+6.2*7.6=4.8*3.1+3.1*2*7.6
=3.1*(4.8+15.2)=3.1*20=62
4.8x7.6+52x0.76的簡便方法
4樓:妙酒
4.8x 7.6+52x0.76
=4.8x7.6+5.2x7.6
=(4.8+5.2)x7.6
=10x7.6
=76,

5樓:黎祖南
簡便計算過程方法如下
解:3.7×4.8+6.2×4.8-4.8=4.8x(3.7+6.2-1)
=4.8x8.9
=42.72
6樓:陳長的路上
簡便計算:
3.7×4.8+6.2×4.8-4.8
=4.8x(3.7+6.2-1)
=4.8x8.9
=42.72
7樓:匿名使用者
解:原式
=(3.7+6.2)x4.8-4.8
=(10-0.1)x4.8-4.8
=48-0.48-4.8
=42.72

答:bai原du
式zhi=(
dao3.7+6.2)
回*4.8-4.8
=9.9*4.8-4.8
=(答10-0.1)*4.8-4.8
=48-0.48-4.8
=42.72
