Penjelasan dengan langkah-langkah:
[tex]3 \frac{ 3}{4} - 1 \frac{2}{3} \div 2\frac{1}{2} \\ = \frac{15}{4} - \frac{5}{3} \div \frac{5}{2} \\ = \frac{15}{4} - \frac{ \cancel5}{3} \times \frac{2}{ \cancel5} \\ = \frac{15 {}^{ \times 3} }{4 {}^{ \times 3} } - \frac{2 {}^{ \times 4} }{3 {}^{ \times 4} } \\ = \frac{45}{12} - \frac{8}{12} \: \: \: \: \: \\ = \frac{37}{12} = \boxed{ \red{ 3 \frac{1}{12} }}[/tex]
