Câu 1 : 185,4 - 5,36 = 180,04

Câu 2 : 124,7  : 100  +  45,18

           =  1,247 + 45,18 = 46,427

Câu 2 : 2,3 m + 6,8 m = 91 dm

Câu 3 : 7 m² 4 dm² = 70000 cm² + 400 cm²

                              = 70400 cm²

Câu 4 : 123004,64 : 10000  = 12,300464

Câu 5 : 15% của 370 kg là :

            370 x 15 : 100 = 55,5  ( kg )

              55,5 kg = 55500 g

Câu 6 : 2 m² 3 dm² + 1 m² 35cm²

         = 23000 cm² + 10035 cm²

         = 33035 cm²
