Step-by-step explanation:
Let us assume that the fraction in question is a.
Since it is halfway, therefore a = 3/7 + x where x is the distance between a and 3/7.
Likewise, a = 4/9 - x as a is equidistant from both fractions.
Since a = a, we solve for x.
2x = 4/9 - 3/7
2x = (28–27) / 63
x = 1/126
Therefore
a = 3/7 + 1/126
a = 3/7 + 1/(18*7)
Factoring 1/7
a=1/7 * ( 55/18)
a=55/126
