Answer 2

你好，很高兴回答你的问题：

【（14.5+6.25）÷2.5+0.5】×4.2
=【14.5÷2.5+6.25÷2.5+0.5】×4.2
=【5.8+2.5+0.5】×4.2
=8.8×4.2
=8.8×(4+0.2)
=35.2+1.76
=36.96

Answer 3

[(14.5+6.25)/2.5+0.5]*4.2=[20.75/2.5+0.5]*4.2=[8.3+0.5]*4.2=8.8*4.2=36.96

Answer 4

=[20.75÷2.5+0.5]×4.2
=[8.3+0.5]×4.2
=8.8×4.2
=36.96

Answer 5

=(20.75/2.5+0.5)*4.2
=(8.3+0.5)*4.2
=8.8*4.2
=36.96
