Answer:
5
Step-by-step explanation:

In order to find this you need to find a common denominator. 2/3 and 3/4 common denominator would be 12 and so what you do to the bottom you must do to the top. 2x4 is 8 and 3x3 is 9. that would make 8/12 and 9/12. 8 plus nine is 17 and 12 stays there so the answer is 17/12 which equals 1 and 5/10.
First you would multiply 3/4 by 2 then multiply 1/2 by 4 and get 6/8 and 4/8.
