Explanation
Hyphenate compound numbers from twenty-one through ninety-nine, so “thirty-two,” “forty-two,” “twenty-two,” and “twenty-one” are correct. Fractions such as “one-sixteenth” and “one-half” are also hyphenated when written this way, making B and E correct. In C, both compound numbers are correctly hyphenated. A incorrectly hyphenates “a third” and “another third,” while D should say “one hundred,” without a hyphen.
