Incorrect spelling, explanation: you can’t spell forty-five as fourtyfive because fourty is not the correct spelling of the number 40 in English. In addition, both parts of the word should be separated by a hyphen. When writing compound numbers like forty-five, the hyphen is important for clarity and proper formatting. In this case, forty and five are joined to form a single compound number, and the hyphen connects them. Forty-five is the only correct spelling.

Correct spelling, explanation: the etymology of forty-five is similar to forty itself, which has an interesting history and development. Forty comes from the Old English word féowertig, which means four tens or four tens worth. It is derived from féower, meaning four, and tig, which refers to a grouping of ten. Forty as we know it today was standardized in English, with the -u dropped (making it an exception to the rule) as part of the general evolution of the English language. The number forty-five is simply the combination of forty and five. Fourtyfive is not an actual word in the English language.
