Final answer:
Leon's rate of texting is 8 texts per minute.
Step-by-step explanation:
To find Leon's rate of texting, we need to determine how many texts he sends per minute. In this case, Leon sent 6 texts in 3/4 of a minute. To find the rate, we can divide the number of texts by the amount of time it took.
6 texts divided by 3/4 minute is the same as 6 texts multiplied by 4/3, which equals 24/3, or 8 texts per minute.
Therefore, Leon's rate of texting is 8 texts per minute.
