read the sentence. i spend about half my time, he spends two thirds of his time, and she spends a quarter, or maybe a third, of her time on research. where in the sentence should the writer add a hyphen? i spend about - half my time, he spends two thirds of his time, and she spends a quarter, or maybe a third, of her time on research. i spend about half my time, he spends two - thirds of his time, and she spends a quarter, or maybe a third, of her time on research. i spend about half my time, he spends two thirds of his time, and she spends a quarter, or maybe a - third, of her time on research. i spend about half my time, he spends two thirds of his time, and she spends a quarter, or maybe - a - third, of her time on research.
Answer
Brief Explanations:
Fractions written as words often have a hyphen between the parts. "Two - thirds" is the correct form to show it is a fraction. "Half" and "a third" in this context don't require hyphens in the given usage.
Answer:
B. I spend about half my time, he spends two - thirds of his time, and she spends a quarter, or maybe a third, of her time on research.
