tolong jawab dengan cara nya ya

[tex]2.) \: \: 2 \frac{3}{4} + (5 \frac{1}{3} \times \frac{5}{8} ) - 4 \frac{2}{5} \\ = \frac{11}{4} + ( \frac{16}{3} \times \frac{5}{8} ) - \frac{22}{5} \\ = \frac{11}{4} + \frac{10}{3} - \frac{22}{5} \\ = \frac{165 + 200 - 264}{60} \\ = \frac{101}{60} = 1 \frac{41}{60} \\ 3.) \: \: 6 \frac{2}{3} \div 2 \frac{2}{5} \times 2 \frac{1}{4} \\ = \frac{20}{3} \div \frac{12}{5} \times \frac{9}{4} \\ = \frac{20}{3} \div \frac{27}{5} \\ = \frac{20}{3} \times \frac{5}{27} \\ = \frac{100}{81} = 1 \frac{19}{81} [/tex]
semoga membantu
maaf kalo salah...
