Answer: 167/352. A simple proof, the point mid-way between (5/16) and (7/11) is the average of the two numbers, just as the point midway between 2 and 4 is 3 (the average of them). So, to average, we give both numbers the same denominator and then add them. 16 * 11 = 176. That gives us 55/176 in place of our 5/16 (they're equivalent, plug them into a calulator if you don't believe me) and 112/176. We then add these numbers... and end up with 167/176. But... we still have to divide by 2 to find the average (2 + 4) / 2 = 3, in the simplified example I gave. When we divide by 2, that's the same as multiplying by (1/2). That gives us 167 / 352, and the answer to your question.

first multiply each fraction so that they both have same denominators
5/16 x 11/11 = 55/176
7/11 x 16/16 = 112/176
112 - 55 = 57, half of 57 is 28.5
112 - 28.5 = 83.5
55 + 28.5 = 83.5
83.5/176 is halfway between 5/16 and 7/11

167/352. why are you doing math in the summer? get a graphing calculator, add your two fractions together, divide by two, change it back into a fraction and you get 167/352. honestly its not that hard...
