Question

Find the products of the following multiplication using associative property of multiplication.

• A. $4x2518x25$
• B. $5x4231x60$
• C. $50x8x4x250$
• D. $625x1234x8$

Answer 1

The correct option is C $50x8x4x250$

$\left(a\right)4\times (2518\times 25)=4\times (25\times 2518)$ by commutative law

$=(4\times 25)\times 2518$ by associative law

$=100\times 2518=2,51,800$

$\left(b\right)5\times (4231\times 60)=5\times (60\times 4231)$ by commutative law

$=(5\times 60)\times 4231$ by associative law

$=300\times 4231=12,69,300$

$\left(c\right)50\times (8\times 4\times 250)=50\times (8\times 1000)$

$=(50\times 8)\times 1000$ by associative law

$=400\times 1000=4,00,000$

$\left(d\right)625\times (1234\times 8)=625\times (8\times 1234)$

$=(625\times 8)\times 1234$ by associative law

$=5,000\times 1234=61,70,000‬$
