​

Answer 1

Bagian a

[tex](3 \frac{1}{4} \div 2 \frac{3}{4} ) + 1 \frac{1}{2} \\ \\ = ( \frac{13}{ \cancel4} \times \frac{ \cancel4}{11} ) + \frac{3}{2} \\ \\ = \frac{13}{11} + \frac{3}{2} \\ \\ = \frac{26 + 33}{22} \\ \\ \color{aqua}{ = \frac{59}{22} = 2 \frac{15}{22} }[/tex]

Bagian b

[tex]2 \frac{2}{3} +1 \frac{4}{5} - \frac{5}{6} \\ \\ = \frac{8}{3} + \frac{9}{5} - \frac{5}{6} \\ \\ = \frac{80 + 54 - 25}{30} \\ \\ \color{aqua}{ = \frac{109}{30} = 3 \frac{19}{30} }[/tex]
