Помогите решить пример

Answer 1

$1)0.128 div 3.2 = 0.04 \ 2)0.04 + 0.86 = 0.9 \ 3) frac{5}{6} times 1.2 = 1 \ 4)1 + 0.8 = 1.8 \ 5)0.9 div 1.8 = 0.5 \ 6)1 times frac{32}{63} - frac{13}{21} = frac{95}{63} - frac{39}{63} = frac{56}{63} = frac{8}{9} \ 7) frac{8}{9} times 3.6 = 3.2 \ 8)0.505 times frac{2}{5} = 0.202 \ 9)0.202 - 0.002 = 0.2 \ 10)3.2 div .02 = 16 \ 11)5 times 0.5 times 16 = 40$
