Well, first you obviously need two completely different fractions , for example; I'll use two sevenths and three ninths. You "always" need to put a line with a numerator and a denominator otherwise its not really cross multiplying.

Well, if you had the fractions seven eighths and nine sixteenths, you will cross multiply. So, you multiply the 7 and the 16 and it equals 112. So you put the product beside the fraction seven eighths. Then, you multiply the 9 and the 8 and you will get 72. Then you put the other product beside nine sixteenths and the fraction that has a greater number beside it is greater. So my inequality for this problem is greater than.

Cross multiplying helps you do it faster. An example is 4/8 and 5/3. You write them next to each other, then multiply the 4 and 3 which should give you 12. Next you multiply the 5 and 8 which should give you 40. Last you see which number is bigger and it is 40 so 5/3 is bigger than 4/8.

Cross multiplying helps you compare fractions by telling you which fraction is larger. You multiply the first denominator times the second numerator and the second denominator times the first numerator. You place the product above the numerator that you use. Then, you see which product is larger and that tells you which fraction is larger. If the product is the same, then the fractions are equal.

Cross multiplication is a strategy that will assist you when you have already drawn a picture but you still aren't sure if it's correct.For example 3/7 and 4/5.You could use cross multiplication.Though there are a few things you always have to do while using cross multiplication like multiply the numerator to the denominator it is very useful.

Cross multiplying helps you check over it to see if you got it right. An example is 5/6 and 7/8. You would multiply 8 x 5 and 7 x 6. Then, you would see which one is bigger. That is how you do it.

Cross multiplication is a way you compare fractions .it can be used to check your work.for example if you 2/5 and 2/6 you would draw a diagonal line from the 2 and the 6 and the 2 and 5.Then you would multiply the numbers.that will tell you your awnser

Cross multiplying will come and help you because it tells you if the inequality is < ( less than ) or > ( more than ).

The cross multiplication method helps us in many ways. Like with fraction problems . One example is two sixth and three forths. Frist i would multiply the two and the four which give me eight . Also the six and the three are multiplyed which is eightteen now I look at the greater number and the greater number is eightteen.
