3/4
Explanation:
Will make those 2 fractions have the same denominator by finding an equivalent fraction for 2/3
2/3 = 2*2/ 2*3 = 4/6
Half way between 4/6 and 5/6 is 4.5 /6
4.5/6 if we double it is the same as 9/12
9/12 = 3*3/ 3*4 = 3/4 is simplified 4.5/6 or 9/12
The rational number halfway between 2/3 and 5/6 is 3/4
