Answer:
59/6
Step-by-step explanation:
- Multiply 3/4 with 12
- 12 x 3 will become 36 and divided by 4 is 9
- 9 + 5/6 cannot be added because they do not have the same denominator.
- Next you have to multiply 9/1 with 6/6 so that it has the same denominator as 5/6
- The problem will now become 5/6 + 54/6
- Now you can add the numerators and get the answer
- The answer is59/6
