a)

• 14.50 = (14:2) . (50.2) = 7.100 = 700

              Vậy 14.50 = 700.

• 16.25 = (16:4) . (25.4 ) = 4.100 = 400

              Vậy 16.25 = 400.

b)

• 2100:50 = (2100.2) : (50.2) = 4200 : 100 = 42

              Vậy 2100:50 = 42.

• 1400:25 = (1400.4) : (25.4) = 5600 : 100 = 56

              Vậy 1400:25 = 56.

c) 

• 132:12 = (120 + 12) : 12 = 120:12 + 12:12 = 10 + 1 = 11

               Vậy 132:12 = 11.

• 96:8 = (88 + 8): 8 = 88:8 + 8:8 = 11 + 1 = 12

               Vậy 96:8 = 12.
