Answer: The sum that is equivalent to 3/5 + 1/6 is 18/30 + 5/30.
Explanation:
This is because both 18/30 and 5/30 can be simplified to 3/5 and 1/6 respectively.
18/30 can be simplified by dividing both numerator and denominator by 6, which results in 3/5.
5/30 can be simplified by dividing both numerator and denominator by 5, which results in 1/6.
So 18/30 + 5/30 = 3/5 + 1/6.
The other options are not equivalent, 6/10 + 2/10 is equivalent to 4/5, 12/30 + 5/30 is equivalent to 17/30 and 3/11+4/11 is equivalent to 7/11
