To find the half-way fraction between two fraction, we need to add the two fractions and divide the sum by 2.

3/7 + 4/9

In adding fractions, denominators must be the same.

3/7 * 9/9 + 4/9 * 7/7

27/63 + 28/63 = (27+28)/63 = 55/63 

55/63 ÷ 2 = 55/63 * 1/2 = 55/126

55/126 is the fraction half-way between 3/7 and 4/9

3/7 = 0.4286
4/9 = 0.4444

0.4286 + 0.4444 = 0.873
0.873 ÷ 2 = 0.4365

55/126 = 0.4365
