Answer 1

$(1) : frac{1}{5} : and : frac{1}{25}$
$(2) : frac{3}{8} : (otvet : 2)$
$(3) : frac{15}{150} = frac{1}{10}$
$(4) frac{2}{3} + frac{1}{6} + frac{1}{4} = \ = frac{8 + 2 + 3}{12} = frac{13}{12} = 1 frac{1}{12}$
$(5)1 - ( frac{1}{3} + frac{2}{9} ) = \ = 1 - ( frac{3 + 2}{9} ) = frac{4}{9}$


(6) А-3 ; Б-1; В-4

$frac{18}{35} times frac{7}{6} = frac{21}{35} = frac{3}{5} \ 2 frac{2}{5} div frac{3}{10} = frac{12}{5} times frac{10}{3} = 8 \ (1 frac{1}{4} ) ^{2} = ( frac{5}{4} ) ^{2} = frac{25}{16} = 1 frac{9}{16}$
