Question

Find the value using suitable property and mention the property used a) 473 x 119 – 19 x 473 b) 445 x 96 c) 577 x 1004 d) 972 x 12 - 972 x2​

Answer 1

Answer:

$a) \: 473 \times 119 - 19 \times 473$

$= 473 \times (119 - 19)$

using distributive property

$= 473 \times 100$

$= 47300$

$b) \: 445 \times 96$

$= 445 \times (100 - 4)$

$= (445 \times 100) - (445 \times 4)$

using distributive property

$= 44500 - 1780$

$= 42720$

$c) \: 577 \times 1004$

$= 577 \times (1000 + 4)$

$= (577 \times 1000) + (577 \times 4)$

using distributive property

$= 577000 + 2308$

$= 579308$

$d) \: 972 \times 12 - 972 \times 2$

$= 972 \times (12 - 2)$

using distributive property

$= 972 \times 10$

$= 9720$

hope it helps

Answer 2

Step-by-step explanation:

Using distributive property

a)

$473 \times (119 - 19)$

$473 \times 100$

$47300$

b)

$445 \times (100 - 4)$

$44500 - 1780$

$42720$

c)

$577 \times (1000 + 4)$

$577000 + 2308$

$579308$

d)

$972 \times (12 - 2)$

$972 \times 10$

$9720$
