solidus (⁄)
Definition - The ⁄ character. It is used to separate shillings from pence (e.g. 12⁄6) and to display ratios and fractions (e.g. 987⁄654).

Notes:
1. The solidus's slope (⁄) is less than that of the forward slash (/).
2. Unlike the forward slash, the solidus is not found on standard keyboards.

Etymology -
The word derives from the Late Latin solidus, which denoted a Roman coin that was worth about 25 denarii. It ultimately derives from the phrase nummus solidus, which literally means "solid coin."

Oxford English Dictionary -
The term's first citation is from 1891. Its first full citation is from 1898:
"The symbols ⁄ (solidus notation) and : (ratio notation) are equivalent to ÷."
(G. Chrystal Introd. Algebra i. (1902) 3)
