Give an example of a situation where finding the cross product of two sets is useful & explain why it is useful

Question

Your example should include two sets and their cross product

This is what I have so far:

Cross product is useful when deicing what to wear because you can mix and match outfits

A=pink shirt, red shirt, white shirt

B=black pants, gray pants, brown pants

 

Answer 1

Is 21/43 less than 15/31?

cross multiply and you get 21(31) = 651 and 43(15) = 645

21/43 > 15/31 because 651>645

You're buying some grocery foot. the can or package tells

you how many total calories or carbs per grams

21 carbs per 43 gram and 15 carbs per 31 grams

If you're trying to minimize carbs, which package or can should you buy
