Identify the property of multiplication used in the given equation.
15 x (3 x 2) = (15 x 3) x 2
That's Correct!
It's Wrong!
Let’s consider the given equation:
15 x (3 x 2) = (15 x 3) x 2
15 x (3 x 2) = 15 x 6 = 90
(15 x 3) x 2 = 45 x 2 = 90
Notice that only the grouping of numbers is different in both the equations, but product is the same.
According to associative property of multiplication, when three or more numbers are multiplied, the grouping of numbers does not affect the product or result.
a x (b x c) = (a x b) x c, where a, b, and c are any numbers (not equal to zero).
So, the associative property of multiplication is used in the given equation.
