To determine the sign of the product of −2/9×1/7, we multiply both fractions.
(-2/9) * (1/7) = -2/63
Since the product is negative (-2/63), we enter – for negative.

The Commutative Property of Multiplication is shown by the statement:
a × b = b × a
This means that the order of the numbers being multiplied does not change the product.
a × b = b × a
This means that the order of the numbers being multiplied does not change the product.
