Question

152✘0.67-14.2✘6.7用简便方法怎么计算?

Answer 1

152乘0.67减14.2乘6.7
等于0.67（152+142）
等于0.67×294
等于196.98

Answer 2

本题简便计算方法是先将152×0.67转换为15.2×6.7，再用分配律计算。公式是a×b-a×c=a×（b-c）
152×0.67-14.2×6.7
=15.2×6.7-14.2×6.7
=6.7×（15.2-14.2）
=6.7×1
=6.7

Answer 3

152×0.67－14.2×6.7=152×0.67－142×0.67=（152－142）×0.67=110×0.67=100×0.67+10×0.67=67+6.7=73.7

Answer 4

计算
152*0.67-14.2*6.7
=152*0.67-142*0.67
=(152-142)*0.67
=10*0.67
=6.7

Answer 5

152x0.67-14.2x6.7
=15.2x6.7-14.2x6.7
=6.7x（15.2-14.2）
=6.7x1
=6.7
