Answer: The number is 4/6.
Step-by-step explanation:
We have that the numbers in the number line are 3/6 and 5/6, and we want to find the number x that is halfway between them.
To do this, te first thing we need to do is calculate the difference between the numbers:
d = 5/6 - 3/6 = 2/6
now, we divide the difference between 2:
d/2 = (2/6)*(1/2) = 1/6
now, we can add this number to the smaller one or subtract it to the larger one to get x:
x = 3/6 + 1/6 = 4/6
x = 5/6 - 1/6 = 4/6
