$\displaystyle (\frac{7}{2},\frac{1}{2})$

Work Step by Step

To find the midpoint between points $(x_1,y_1)$ and $(x_2,y_2)$, we use the midpoint formula: $\displaystyle Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$ We use the points $(21/4,2/5)$ and $(7/4,3/5)$: $\displaystyle Midpoint=(\frac{21/4+7/4}{2},\frac{2/5+3/5}{2})$ $\displaystyle =(\frac{28/4}{2},\frac{5/5}{2})$ $\displaystyle =(\frac{7}{2},\frac{1}{2})$
