Answer 1

[tex] \frac{3}{4} - \frac{7}{20} = \frac{15}{20} - \frac{7}{20} = \frac{8}{20} = \frac{2}{5} [/tex]

[tex] \frac{4}{15} - \frac{1}{6} = \frac{8}{30} - \frac{5}{30} = \frac{3}{30} = \frac{1}{10} [/tex]

[tex] \frac{3}{8} + \frac{1}{40} = \frac{15}{40} + \frac{1}{40} = \frac{16}{40} = \frac{2}{5} [/tex]

[tex] \frac{1}{3} + \frac{1}{15} = \frac{5}{15} + \frac{1}{15} = \frac{6}{15} = \frac{2}{5} [/tex]

[tex]1 \frac{1}{2} \times \frac{2}{3} = \frac{3}{2} \times \frac{2}{3} = 1[/tex]

[tex]5 \times \frac{1}{5} = \frac{5}{1} \times \frac{1}{5} = 1[/tex]

[tex]2 \frac{2}{3} \div 1 = 2 \frac{2}{3} [/tex]

[tex]3 \frac{2}{5} \div \frac{17}{5} = \frac{17}{5} \times \frac{5}{17} = 1[/tex]
