jawaban no 1

$5 = 5.10.15.20.25.30.35.40 \ 4 = 4.8.12.16.20.24.28.32.36.40 \ 8 = 8.16.24.32.40$

$frac{4}{5} times frac{8}{8} = frac{32}{40} \ frac{3}{4} times frac{10}{10} = frac{30}{40} \ frac{3}{8} times frac{5}{5} = frac{15}{40}$

$frac{32}{40} + frac{30}{40} - frac{15}{40} = frac{47}{40}$

$9 = 9.18.27......90\ 18 = 18.36.52...90 \ 5 = 5.10.15....90$

$frac{8}{9} times frac{10}{10} = frac{80}{90} \ frac{5}{18} times frac{5}{5} = frac{25}{90} \ frac{4}{5} times frac{18}{18} = frac{72} {90}$

$frac{80}{90} div frac{25}{90} + frac{72}{90} = frac{75.2}{90}$

semoga membantu
