Answer:
The correct option is C) 7/3.
Step-by-step explanation:
Consider the provided numbers.
If the rational number can be written in the form of [tex]\frac{p}{2^n\times 5^m}[/tex] then the rational number will be a terminating decimal.
Now consider the provided options:
Option A) 7/5 can be written as: [tex]\frac{7}{2^0\times 5^1}[/tex]
Thus it is a terminating decimal.
Option B) 7/4 can be written as: [tex]\frac{7}{2^2\times 5^0}[/tex]
Thus it is a terminating decimal.
Option C) 7/3 can be written as: [tex]\frac{7}{2^0\times 5^0\times 3^1}[/tex]
Thus it is not a terminating decimal.
Option D) 7/2 can be written as: [tex]\frac{7}{2^1\times 5^0}[/tex]
Thus it is a terminating decimal.
Hence the only fraction that must be represented by a non terminating decimal is 7/3.
The correct option is C) 7/3.
