Communicate jason has 3 bags with 5 mangos in each bag. maria has 5 bags with 4 mangos in each bag. explain how you can tell who has more without finding the total number of mangos each person has.

We know that

This problem would require adding or multiplying, without calculating the total number of mangos, we can look at the numbers given to us and tell that Maria must have more than Jason because 5 with 4 is more than 5 with 3 (whether adding or multiplying)

another way to solve the problem

I can say that 3 bags with 5 mangos is> 3/5
and
5 bags with 4 mangos it's the same from the numerical point of view as saying 4 bags with 5 mangos> 4/5

I compare fractions with the same denominator and the greater one will be the one with the highest numerator
therefore
4/5 is > 3/5 
Maria must have more than Jason
