The fraction represented by the shaded portion in the adjoining figure is \(\tfrac{3}{8}\).
Idea: A fraction tells parts shaded out of total equal parts.
Step 1: Count the total equal parts of the circle.
( ext{total equal parts} = 8)
Step 2: Count how many parts are shaded.
( ext{shaded parts} = 3)
Step 3: Write the fraction.
( ext{Fraction} = dfrac{ ext{shaded parts}}{ ext{total equal parts}})
( ext{Fraction} = dfrac{3}{8})
Step 4 (Check): The statement says the fraction is ( frac{3}{8}), which matches our answer.
Conclusion: The statement is true.
