Questions & Answers

Q: How can we quickly determine the largest fraction out of two given fractions?

To determine the largest fraction, we can use the method of cross multiplication. By cross multiplying the numerators and denominators, we obtain two resulting products. Comparing these products allows us to identify the larger fraction.

Q: What is the significance of cross multiplication in this method?

Cross multiplication helps us compare the sizes of the fractions by examining the resulting products. The larger product indicates the larger fraction.

Q: Can this method be applied to fractions with different denominators?

Yes, the method works regardless of the denominators being different. By multiplying the numerator of one fraction with the denominator of the other and vice versa, we can compare the resulting products to determine the largest fraction.

Q: Are there any limitations to this method?

This method only works for comparing two fractions at a time. It does not provide a solution for multiple fractions or ordered sets.
