Question

How do I write these

Answer 1

You might be able to get the text-to-speech option on your phone to do this for you, since it involves saying the fractions aloud.

1/2 ⇒ one-half

2/3 ⇒ two thirds

1/4 ⇒ one quarter, or one fourth

2/4 ⇒ two fourths, or two quarters

2/5 ⇒ two fifths

5/6 ⇒ five sixths

4/7 ⇒ four sevenths

6/8 ⇒ six eighths

5/11 ⇒ five elevenths

1/12 ⇒ one-twelfth

1/20 ⇒ one-twentieth

IMO, the use of a hyphen or not depends on the context. If the fraction itself is the focus, you might say one twelfth. If it is describing a portion of something else, you might say one-twelfth [of a cake].
