Write Math Right
Consider this old query: Can you read the following or write them in words so there is no mistaking the amount expressed?
Item A. 2.0⅔
Item B. 0.2⅔
In the 1940s, a teacher, Kate Savage, told students that any fractional amount less than a whole takes the singular form, plus any common fraction holds no place value system but acts as a "tail attached to the previous place."
By her view, Item A should be read "two and two-thirds tenth" and Item B as "two and two-thirds tenths."

What about 0.7½...is it 0.75? Or 0.00½...does it become 0.005? If so, what would you do with 0.½? Is it 0.5 or 0.05? Be careful, as ½ without a decimal point is 0.5. By Kate Savage's reasoning, the ½ in 0.½ is attached to the one's place, thus...
Isn't it fun how such simple questions can bother us and provide fun for more than 50 years!
