×6.7=16.08.分析:乘法算式中,积扩大(缩小)的倍数等于两个因数扩大(缩小)的倍数的积(两因数不为0);
一个因数不变,另一个因数扩大或缩小几倍(0除外),积也就扩大或缩小相同的倍数;据此解答.
一个因数不变,另一个因数扩大或缩小几倍(0除外),积也就扩大或缩小相同的倍数;据此解答.
解答:解:因为37×416=15392,所以:
3.7×4.16=15.392
0.37×416=153.92
0.037×4.16=0.15392
0.37×0.00416=0.0015392
2.4×6.7=16.08.
故答案为:15.392,153.92,0.15392,0.0015392,2.4.
3.7×4.16=15.392
0.37×416=153.92
0.037×4.16=0.15392
0.37×0.00416=0.0015392
2.4×6.7=16.08.
故答案为:15.392,153.92,0.15392,0.0015392,2.4.
点评:此题主要考查乘法算式中两个因数的变化引起积的变化规律.
