The number 185 is spelled out as one hundred eighty-five.
It should not contain words besides the numbers, such as and (and is only used to express fractions or decimals after the whole number). There should be a dash between the tens and ones spot.

Second answer (reference Oxford English)
One hundred and eighty-five is correct in Oxford English. I presume some places may have different rules about how numbers should be written.
If the two last digits of a number that is three or more digits long are not "00", it is grammatically correct to add "and". Here are several examples.
The rule may differ elsewhere. There is a lot of conflicting information due to different forms of the English language, but what I have explained is the standard Oxford English rule.

Grammatically speaking, the number 185 is spelt one hundred and eighty-five, when spoken aloud and written.
In writing, if you wrote it as "one hundred eighty-five", it does not sound right nor does it sound like how you would normally pronounce it in numerical form.
