The product of two mixed numbers that are each between 5 and 4 is the product between 16 and 25
Alchen [17]
Hmm
that is a true statement, the product of any 2 mixed numbers between 4 and 5, will be between 16 and 25

we can show that it is true by testing the bounds
if the number is 4 and the other is 4, then it is 16
we aren't allowed to do 4 since it isn't mixed and it equals 4
that is the lower bbound

if the numbes 5 and 5 are used, then it is 25
we arene't allowed to use 5 since it isn't mixed and it equals 5

so the product of any 2 numbers between 4 and 5 will be between 16 and 25

so pick any random one
