Answer
$(10\times2)\times y$
Work Step by Step
The associative property holds that $(a\times b)\times c= a\times(b\times c)$, where a, b, and c are real numbers.
In this example, we can set $10\times(2\times y)=a\times(b\times c)$.
So, $a=10$, $b=2$, and $c=y$.
Therefore, the other side of this equation is $(a\times b)\times c=(10\times2)\times y$.
