Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid using preposition 'in' before percent (e.g., NOT 'growth in 5 percent', but 'growth of 5 percent' or 'growth by 5 percent').
- Remember that 'percent' is not declined in English (no 'percents').
- The word 'interest' in financial contexts is not the same as Russian 'интерес'.
Common Mistakes
- Using a plural verb with a singular subject (e.g., 'Fifty percent of the budget are allocated' - should be 'is allocated' unless referring explicitly to plural people/items).
- Writing 'percents'.
- Confusing 'percent' (proportion) with 'percentage point' (absolute difference).

FAQ
Frequently Asked Questions
Both are correct. 'Percent' is standard in American English and increasingly common in British English. 'Per cent' is the traditional British form but is less frequent now.
It depends on the noun that follows 'of'. If the noun is uncountable or singular, use a singular verb (e.g., 'Percent of the water is...'). If the noun is plural, use a plural verb (e.g., 'Percent of the students are...').
A 'percent' is a relative measure (1/100). A 'percentage point' is an absolute difference between two percentages. For example, an increase from 5% to 10% is a 5 percentage point increase, or a 100 percent increase.
Informally, yes, especially in American English (e.g., 'I agree with you one hundred percent'). However, in formal writing, it is primarily treated as a noun.
