Caleb stirred one-fourth of the walnuts into the batter.

The scientist added one eighth of a teaspoon of salt to the solution.

Answer 1

Correct: 1, 2, and 3.

Why:
- Sentence 1: "twenty-four" is a compound number (21–99) and is correctly hyphenated.
- Sentence 2: "more than one hundred" is correct — "one hundred" is not hyphenated here.
- Sentence 3: "one-fourth" is a spelled-out fraction and is correctly hyphenated.

Incorrect:
- Sentence 4 should be "There are three hundred kids in my high school." (no hyphen)
- Sentence 5 should be "The scientist added one-eighth of a teaspoon of salt to the solution." (hyphenate the fraction)
