So you can easily look at all of them and see the least to greatest. So for A. it is wrong because 7. 41 is bigger/greater than 7.6... The reason why B is out because 7.6 is lower than 7 4/5=7.8. That is why B and A is out. So D was like a automatic OUT, because you don't even have to solve the fraction cause the lowest is on the greatest side. And C is out too because 7.41 is the greatest.
An even number is a number that is divisible by 2. This means that dividing this number by 2 yields no remainder (the remainder is zero).
The even numbers between 7 and 16 are: 8 as 8/2 = 4 and remainder is zero 10 as 10/2 = 5 and remainder is zero 12 as 12/2 = 6 and remainder is zero 14 as 14/2 = 7 and remainder is zero
