How can you tell from the fraction array of fractions are equivalent?

You can determine if fractions are equivalent by simplifying them to their lowest terms or by comparing their cross products. If two fractions simplify to the same value or if the cross products (the product of the numerator of one fraction and the denominator of the other) are equal, then the fractions are equivalent. For example, for fractions a/b and c/d, they are equivalent if a * d = b * c.
