脱式计算:
5/6×65+5÷6
=5/6×65+5/6
=5/6×(65+1)
=5/6×66
=55
3/5+2/5÷6/7
=3/5+7/15
=16/15
第一个脱式计算,5/6×65+5÷6=325/6+5/6=330/6=55
第二个图是计算,3/5+2/5÷6/7=3/5+2/5×7/6=3/5+7/15=9/15+7/15=16/15
很简单答案就是这样
5÷6×65+5÷6=55
3÷5+2÷5÷6÷7=0.6095238095238096
一般单号是靠窗户的。你也可以上去跟别人调换一下。
5/6×65+5÷6
=5/6×65+5/6×1
=5/6×(65+1)
=5/6×66
=55
3/5+2/5÷6/7
=3/5+7/15
=9/15+7/15
=16/15
