Is the word frutas the same in Brazilian and European Portuguese?

Yes

The word "frutas" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, vowels tend to be more open and clearly articulated. In Continental Portuguese, unstressed vowels (like the "u" in frutas) are often "reduced" or "swallowed," making them sound much more closed or nearly silent in rapid speech. Additionally, the "s" at the end of the word may be pronounced as a soft [s] in many parts of Brazil, whereas in much of Portugal, it is pronounced as a [ʃ] (like "sh").
