Final answer:
Sentences A, C, and E are punctuated correctly, using hyphens for compound numbers and fractions. Sentences B and D contain errors in hyphenation and word choice.
Step-by-step explanation:
The punctuated sentences correctly are:
- A) Ms. Washington bought twenty-four pencils for the classroom.
- C) Caleb stirred one-fourth of the walnuts into the batter.
- E) The scientists added one eighth of a teaspoon of salt to the solution.
These sentences correctly use hyphens for compound numbers and fractions. Sentence B incorrectly uses 'more that' instead of 'more than'. Sentence D is incorrect because 'three-hundred' should be 'three hundred' without a hyphen.
