Answer 2

Answer:

1.

679 x 8 + 679 x 2

= 679 × ( 8+2)

= 679 × 10

= 6790

PROPERTY APPLIED : DISTRIBUTIVE

2.

8324 x 1945 - 8324 x 945

= 8324 × ( 1945 - 945)

= 8324 × 1000

= 8324000

PROPERTY APPLIED : DISTRIBUTIVE

3.

15 x 49372

4: 25 x 444 x 4

= 444 × 25 × 4

= 444 × 100

= 44400

PROPERTY APPLIED : COMMUTATIVE UNDER MULTIPLICATION

5.

162 + 253 + 338 + 47

= 162+338+253+47

= 500 + 300

= 800

PROPERTY APPLIED : COMMUTATIVE UNDER ADDITION

6.

548 x 98

= 548 × ( 100 - 2)

= 548×100 - 548×2

= 54800 - 1096

= 53704

PROPERTY APPLIED : DISTRIBUTIVE
