Question

Grupează convenabil factorii, pentru a calcula mai rapid: Model: 236 x 5 x 2 = 236 x (2 x 5) = 236 x 10 = 2360 4 x 65 x 25 = 5 X 884 X 2= 2 x 250 x 5 = 25 X 80 X4= 2 x 582 x 5 = 4 x 73 x 25 = repede va rog dau coroana​

Answer 1

4 × 65 × 25 = 65 × ( 4 × 25 ) = 65 × 100 = 6500

5 × 884 × 2 = 884 × ( 5 × 2 ) = 884 × 10 = 8840

2 × 250 × 5 = 250 × ( 2 × 5 ) = 250 × 10 = 2500

25 × 80 × 4 = 80 × ( 25 × 4 ) = 80 × 100 = 8.000

2 × 582 × 5 = 582 × ( 2 × 5 ) = 582 × 10 = 5820

4 × 73 × 25 = 73 × ( 25 × 4 ) = 73 × 100 = 7300
