tolong di jawab ya kak 4 sampai 8

[tex]5. \: (1 \frac{1}{3} \times \frac{1}{4} ) + \frac{1}{5} = ( \frac{4}{3} \times \frac{1}{4} ) = \frac{1}{3} \\ \frac{1}{3} + \frac{1}{5} = \frac{5}{15} + \frac{3}{15} = \frac{8}{15} \\ \\ 6. \frac{1}{3} \times \frac{12}{1} = 4 \\ \\ 8. \frac{1}{5} \times \frac{9}{20} = \frac{9}{100} [/tex]

semoga membantu
