Distributive Property

Find the product by using distributive property:

7 x 81 =

• = 7 x (80+1)

  = (7x80) + (7x1)

  = 560 + 7

  = 567

• = 7 x (80-1)

  = (7x80) - (7x1)

  = 560 - 7

  = 553

• = 8 x (7+1)

  = (8x7) + (8x1)

  = 56 + 8

  = 64

Fill the blanks:

21 x 5 = 5 x (.......+ .......)

• 21 + 5

• 20 + 1

• 20 - 1

• 21 - 5

Fill in the blanks:

71 x 8 = 8 x (70+1)

= (.................) + (8 x 1)

• 7 + 80

• 7 x 80

• 8 x 70

• 8 + 70

What is the product of:

60 x 4=

• 24

• 42

• 420

• 240

Fill in the blank:

................. = 2 x (80 + 6)

• 2 x 86

• 80 x 6

• 2 x 6

• 80 + 6

Find the product by using distributive property:

84 x 8=

• = 8 + (80x4)

  = (8+80) x (8+4)

  = 88 x 12

  = 1056

• = 8 x (80+4)

  = (8x80) + (8x5)

  = 640 + 40

  = 680

• = 8 x (80+4)

  = (8x80) + (8x4)

  = 640 + 32

  = 672

• = 8 x (80-4)

  = (8x80) - (8x4) = 640 - 32

  = 608

Fill the blanks:

15 x 5 = ....... x (.......+.......)

• 5 x (15+5)

• 5 x (10+5)

• 5 x (10x5)

• 15 x (10+5)

Find the product:

80 x 6=

• 48000

• 48

• 480

• 4800

Complete the next step:

34 x 2 = 2 x (30+4)

=..................+ ...................

• (2x30)+ (2x34)

• (2x30)+ (2x4)

• (2+30)x (2+4)

• (2x34)+ (2x4)

Fill in the blank:

83 x 9 = 9 x (80+3)

= (9x80) + (9x3)

= ...........+........... = .............

• 720 + 270 = 990

• 720 + 27 = 99

• 72 + 27 = 99

• 720 + 27 = 747
