The method of cross multiplying is a valid way to compare fractions effectively. When comparing two fractions, for example, a/b and c/d, cross multiplication involves multiplying the numerator of the first fraction (a) by the denominator of the second fraction (d) and the denominator of the first fraction (b) by the numerator of the second fraction (c). This results in two products: ad and bc. Comparing these two products allows you to determine which fraction is larger or if they are equal without needing to find a common denominator or convert them to decimal form.

Using cross multiplication can be particularly useful because it simplifies the comparison process, especially when dealing with fractions that may have different denominators. The method emphasizes the multiplicative relationship between the fractions, providing a straightforward means to arrive at a conclusion about their relative sizes.

While other methods, such as finding common denominators or subtracting fractions, can be used in fraction operations, they are not typically employed solely for comparison. Thus, cross multiplying stands out as an efficient and effective technique for determining the relationship between two fractions.
