Answer:
1:8
Step-by-step explanation:
Given that in square ABCD, point M is the midpoint of side AB and point N is the midpoint of side BC.
Let the side of the square be a.
Area of square ABCD = 
The triangle AMN is having two legs of a right triangle as half of side of the square
i.e. Triangle AMN has base = height = a/2
So area of triangle AMN = 
Ratio of the area of triangle AMN to area of square ABCD
= 1:8
Here, we want to select which of the fractions are rational
To get this, we need to understand what rational numbers are
Rational numbers are numbers that can be expresed in form a/b where the value of b is not equal to zero
From the options in the question, we can see that all these numbers are directly expressed as fractions in the form a/b with none of the denominators being eual to zero
This means all the given fractions are rational
