$x=9 7/10$

Let the third number be $x$

SO $9 1/2 +9 3/4 + x = 28 19/20$

$x=28 19/20-9 1/2-9 3/4$ (put these numbers into a calculator)

$x=9 7/10$

The sum of three mixed numbers is 28\frac { 19} { 20}28\frac { 19} { 20}. Two of the numbers are 9 1/29 1/2 and 9 3/49 3/4. What is the third number?
