Answer 2

I can help you with some math problems. Here are the detailed solutions for your questions:

1) $$1 \frac{1}{4} \times \frac{2}{5} - \frac{1}{3} = \frac{5}{4} \times \frac{2}{5} - \frac{1}{3} = \frac{10}{20} - \frac{1}{3} = \frac{10}{20} - \frac{5}{15} = \frac{10 - 10}{60} = 0$$

2) $$\frac{5}{6} : \frac{1}{3} + 1 \frac{3}{8} = \frac{5}{6} \times \frac{3}{1} + \frac{11}{8} = \frac{15}{6} + \frac{11}{8} = \frac{60}{24} + \frac{33}{24} = \frac{93}{24} = 3 \frac{21}{24} = 3 \frac{7}{8}$$

3) $$2 \frac{1}{3} : 1 \frac{5}{9} - \frac{5}{6} = \frac{7}{3} : \frac{14}{9} - \frac{5}{6} = \frac{7}{3} \times \frac{9}{14} - \frac{5}{6} = \frac{63}{42} - \frac{5}{6} = \frac{63}{42} - \frac{35}{42} = \frac{28}{42} = \frac{2}{3}$$

4) $$\frac{4}{9} + 1 \frac{2}{3} + 2 \frac{5}{9} + \frac{1}{3} = \frac{4}{9} + \frac{5}{3} + \frac{23}{9} + \frac{1}{3} = \frac{4 + 15 + 23 + 3}{9} = \frac{45}{9} = 5$$

5) $$1 \frac{3}{10} + \frac{1}{4} + 2 \frac{7}{10} + \frac{3}{4} = \frac{13}{10} + \frac{1}{4} + \frac{27}{10} + \frac{3}{4} = \frac{52}{20} + \frac{5}{10} + \frac{54}{20} + \frac{15}{20} = \frac{126}{20} = 6 \frac{6}{20} = 6 \frac{3}{10}$$

I hope this helps. If you have any other questions, feel free to ask me.
