Question

add 2/3, 3/4 and 5/6​

Answer 1

Answer:

27/12 or 9/4

Step-by-step explanation:

you change the denominators to 12 because 3, 4 and 6 are all factors of 12.

therefore, 2/3 is multiplied by 4 to give 8/12

3/4 is multiplied by 3 to give 9/12

8/6 is multiplied by 2 to give 10/12

now you simply add:

8/12 + 9/12 + 10/12 = 27/12

now you can reduce it to 9/4 because 3 is a factor of 27 and 12

Answer 2
