[tex] \tt \: \frac{3}{4} + 1 \frac{1}{2} [/tex]
[tex] \tt \: = \frac{3}{4} + \frac{(2 \times 1) + 1}{2} [/tex]
[tex] \tt \: = \frac{3}{4} + \frac{3}{2} [/tex]
[tex] \tt \: = \frac{3}{4} + \frac{3 \times 2}{2 \times 2} [/tex]
[tex] \tt \: = \frac{3}{4} + \frac{6}{4} [/tex]
[tex] \tt = \frac{9}{4} [/tex]
