Đặt lại phép tính: đơn vị thẳng đơn vị, chục thẳng chục rồi tính kết quả.

nhớ trong gia đình tôi thường ăn kem sau bữa tối 

giúp mình phép tính này với : ( 84,6 -2 x X ) : 3,02 = 5,1

( 84,6 - 2 x X ) : 3,02 = 5,1

( 84,6 - 2 x X ) = 15,402

2 x X = 84,6 - 15,402

2 x X = 69,198

      X = 69,198 : 2

      X = 34,599

hok tốt ^^

Hướng dẫn giải:

a) 572 : 35 = 16 (dư 2)

b) 31730 : 15 = 2115 (dư 5)
