I am interpreting your question as 7 * 3/4. First we multiply 7 and 3 together to get 21. Now we divide 21 by 4. Because 21 isn't divisible by 4 and they share no common factors, 21/4 is our answer.
To find the answer you have to see how many words see can type in a minute. To do that you can divide 90 into 12. You will get an answer of 7.5. Now that you know she can type 7.5 words per minute you can divide 165 in to 7.5. Will get an answer of 22. She will take 22 minutes to text 165 words.
(5raise to power 5)÷(4)=3125/4)
