From something I read:
“Los datos son contundentes: entre 2013 y 2018, el turismo de bienestar ha crecido a un ritmo anual de 15%.”
I often see “el,” “un” before percentages. Here, there is neither, as one can see. Is it optional? Would it also have been correct, for example, to have said “...ha crecido a un ritmo anual del 15%.”?
