Hi Emily!!! For this question, before I could add the fractions, I had to make all of them have the same denominator or bottom number. So in this case, I needed each denominator to be a 12. The fractions are 3/4, 7/6 and 2/3. Starting with the first fraction, 3/4, let's change the 4 to a 12. In order to do that I need to multiply the 4 by 3 to get 12. However, I also need to change the numerator or top number of the fraction because I changed the denominator. So I have to multiplied the 3 by 3 also to get 9. Now my first fraction is no longer 3/4 it's 9/12. Let's do the same process for the second fraction, 7/6. The 6 will be multiplied by 2 to get 12. Now multiply the 7 by 2 to get 14. The second fraction is now 14/12. Lastly, the third fraction is 2/3. I multiplied both numbers by 4. The third fraction goes from 2/3 to 8/12. I hope this make sense now. Please let me know. Thanks, Mrs. Taylor

Hi there!!! On a basic calculator or a 4 function calculator, you should have the radical symbol as one of the buttons. In Google, type “radical symbol” to see what it looks like. You would use that button to calculate the square root of a number. I hope this helps.
