Answer 1

脱式计算方法如下

1、提取原式: (18.62-2.64ⅹ4.3)÷0.24

2、计算过程: 

= (18.62-2.64ⅹ4-2.64ⅹ0.3)÷0.24

= (18.62-10.56-0.792)÷0.24

=(18.62-10.52-0.832)÷0.24

=(8.1-0.832)÷0.24

=(8.1-1+0.168)÷0.24

=7.268÷0.24

≈30.28

3、计算结果: 约 30.28

Answer 2

(18.62-2.64*4.3)÷0.24
=(12+6+0.6+0.02-2.4*1.1*4.3)/0.24
=50+25+2.5-4.3*11+1/12
=77.5-43-4.3+1/12
=34.5-4.3+1/12
=30+1/5+1/12
=30+（12+5）/60
=30又17/60

Answer 3

(18.62－2.64×4.3)÷0.24
＝(18.62－11.352)÷0.24
＝7.268÷0.24
＝30.283'（3上加一点）
