To find out how many words Tatyana can text in 12 minutes, we first need to determine her texting rate in words per minute.
Tatyana texts 225 words in 5 minutes. To find her rate, we can divide the number of words by the number of minutes:
\[ \text{Words per minute} = \frac{225 \text{ words}}{5 \text{ minutes}} = 45 \text{ words per minute} \]
Now, we can find out how many words she can text in 12 minutes:
\[ \text{Words in 12 minutes} = 45 \text{ words per minute} \times 12 \text{ minutes} = 540 \text{ words} \]
Thus, Tatyana can text 540 words in 12 minutes.
