How do you find the midpoint of the line segment joining $(3 \frac{1}{4}, 5 \frac{1}{2}) and (1 \frac{3}{4}, 3 \frac{1}{2})$ $(3 1/4, 5 1/2) and (1 3/4, 3 1/2)$ ?

$(2 \frac{1}{2}; 4 \frac{1}{2})$ $(2 1/2; 4 1/2)$

There is a nifty formula for this:
"Average the x- values and average the y-values."

In Maths: $M (\frac{x_{1} + x_{2}}{2}; \frac{y_{1} + y_{2}}{2})$ $M((x_1 + x_2)/2; (y_1+y_2)/2)$

$(\frac{3 \frac{1}{4} + 1 \frac{3}{4}}{2}; \frac{5 \frac{1}{2} + 3 \frac{1}{2}}{2})$ $((3 1/4 +1 3/4)/2;(5 1/2 +3 1/2)/2)$

$(\frac{5}{2}; \frac{9}{2}) = (2 \frac{1}{2}; 4 \frac{1}{2})$ $(5/2 ;9/2) = (2 1/2; 4 1/2)$

How do you find the midpoint of the line segment joining (314,512)and(134,312)(3 1/4, 5 1/2) and (1 3/4, 3 1/2)?
