Question

6.25×4.3+4.3×7用简便方法怎么算？

Answer 1

根据题意可知:
6.25×4.3+4.3×7
＝4.3×(6.25+7)
＝4.3×13.25
＝(4+0.3)×13.25
＝4×13.25+0.3×13.25
＝53+3×1.325
＝53+3.975
＝56.975

Answer 2

6.25×4.3+4.3×7用简便方法等于4.3×（6.25+7）等于4.3×13.25等于56.975

Answer 3

6.25x4.3+4.3x7
=4.3（6.25++7）
=4.3x13.25
=56.975

Answer 4

原式＝4.3×（6.25+7）
＝4.3×13.25
＝13.25×4+13.25×0.3
＝53+39.75
＝92.75

Answer 5

6.25×4.3+4.3×7
=4.3×（6.25+7）
=4.3×13.25
=56.975
