一道数学题,7.61x9.9+0.761能简算吗?
一道数学题,
7.61x9.9+0.761能简算吗?
一道数学题,7.61x9.9+0.761能简算吗?
7.61x9.9+0.761
=7.61×9.9+7.61×0.1
=7.61×(9.9+0.1)
=7.61×10
=76.1
可以
7.61*9.9+0.761=0.761*9.9*10+0.761=0.761*(99+1)=0.761*100=76.1
7.61x9.9+0.761=7.61(9.9+0.1)=76.1
7.61×9.9+7.61×0.1
=7.61x(9.9+0.1)
=7.61x10
=76.1 希望采纳
原式=7.61x9.9+7.61x0.1=7.61x(9.9+0.1)=76.1
楼上正解
可以,
7.61x9.9+0.761=7.61(9.9+0.1)=76.1
可以啊!!
7.61x9.9+0.761
=7.61x9.9+7.61x0.1
=7.61x(9.9+0.1)
=7.61x10
=76.1
