递等式计算:2.9×(3.8-4/5 )÷(2.375- 5/8)请用小学知识列出递等式计算的步骤
2.9×(3.8-4/5 )÷(2.375- 5/8)
=2.9×(3.8-0.8 )÷(2.375- 0.625)
=2.9×3÷1.75
=174/35=4又(34/35)

2.9×(3.8-4/5 )÷(2.375- 5/8)
=2.9*(3.8-0.8)÷(2.375-0.625)
=2.9*3÷(1.75)
=8.7÷1.75
=174/35

2.9×(3.8-4/5 )÷(2.375- 5/8)
=2.9*(3.8-0.8)÷(2.375-0.625)
=2.9*3÷(1.75)
=8.7÷1.75
=174/35
