Answer 1

$1)7-6,35=7-6frac{35}{100}=7-6frac{7}{20}=7-frac{127}{20}=frac{7*20-127}{20}=frac{13}{20} \ \ 2)frac{13}{20}:6,5=frac{13}{20}:6frac{5}{10}=frac{13}{20}:6frac{1}{2}=frac{13}{20}:frac{13}{2}=frac{13}{20}*frac{2}{13}=frac{1}{10} \ \ 3)frac{1}{10}+9,9=frac{1}{10}+frac{99}{10}=frac{100}{10}=10$

$4)1,2:36=frac{12}{10}*frac{1}{36}=frac{1}{30} \ \ 5)1,2:0,25=frac{12}{10}:frac{25}{100}=frac{12}{10}*frac{100}{25}=frac{24}{5}=4frac{4}{5} \ \ 6)frac{1}{30}+frac{24}{5}-1frac{5}{16}=frac{1}{30}+frac{24}{5}-frac{21}{16}=frac{1*8+24*48-21*15}{240}=frac{845}{240}=frac{169}{48}=3 frac{25}{48} \ \ 7)frac{169}{48}:frac{169}{24}=frac{169}{48}*frac{24}{169}= frac{1}{2} \ \ 8) 10:frac{1}{2}= 10*2=20$
