Fractions and division signs

Where in Windows 10 can be found the fraction signs and divisison etc?

Try Character Map. Click the start button, start typing "Char" and it should be the top item on the list. You will find all the special characters there.

Thank you for your reply,the character map is exactly what I was looking for and so easy
to find ,once you know how.
