Question

Which sentence below expresses numbers correctly?


The average weight of a chocolate bar was one fourth greater in the sixties than today.


“If you 2 don’t settle down right now I am going to turn this car around!” yelled Dad.


There were only twenty four desks for the thirty children in Mr. Clark’s morning kindergarten class.


Did you know that the earth is 4,500,000,000 years old?

Answer 1

Sentence 4.

Explanation and corrections:
- 1 is awkward/hyphenation problem: "one-fourth greater in the sixties than it is today."
- 2 has an extraneous numeral and punctuation issues: "“If you don't settle down right now, I'm going to turn this car around!” yelled Dad."
- 3 needs a hyphen for the compound number: "twenty-four" (…only twenty-four desks…).
- 4 correctly uses numerals and commas for a large number (optionally capitalize Earth: "Did you know that the Earth is 4,500,000,000 years old?").
