Question

Verify the associative property for the multiplication of the following whole numbers :

$3,5,7$

Answer 1

Step $1;$ If $a,b$ and $c$ three whole numbers,

Then, $(a\times b)\times c=a\times (b\times c)$

$(3\times 5)\times 7=3\times (5\times 7)$

Step $2;$ Find the value of $(3\times 5)\times 7$

$=$$(3\times 5)\times 7$

$=$$15\times 7$

$=$ $105$

Step $3;$ Find the value of $3\times (5\times 7)$

$=$ $3\times (5\times 7)$

$=$ $3\times 35$

$=$ $105$

Hence,verified.
