Urgh, that was a shock. I needed to add a column of fractions, like this:
- 1/4
- 1/4
- 1/10
- 1/10
- 1/25
- 1/25
- 1/25
I quickly realised I had not the faintest idea how to do it! Thank goodness for spreadsheets.
An online calculator then converted the sum to a decimal. Hooray!
Update, 17-Sep-2024: in mac OS 15.0 Apple Notes makes this a whole lot easier with Math Notes
: type an expression followed by the equals (=) sign. Done!


@cheribaker I guess I last added fractions as a schoolkid, so over 55 years ago. My first attempt was 1/10+1/10=1/20 … Wait! That can't be right. Then I sought professional help. 😆
