[tex]3 \frac{1}{4} + 2 \frac{1}{2} [/tex]
[tex] = \frac{3 \times 4 + 1}{4} + \frac{2 \times 2 + 1}{2} [/tex]
[tex] = \frac{12 + 1}{4} + \frac{4 + 1}{2} [/tex]
[tex] = \frac{13}{4} + \frac{5}{2} [/tex]
[tex] = \frac{13}{4} + \frac{5 \times 2}{2 \times 2} [/tex]
[tex] = \frac{13}{4} + \frac{10}{4} [/tex]
[tex] = \frac{13 + 10}{4} [/tex]
[tex] = \frac{23}{4} = 5 \frac{3}{4} = 5.75[/tex]
