Question

пожалуйсиа помогите с математикой !!!!!!!!номер 433!!!!!!!!!!!подробно напишите все!!!!!!

Answer 1

$frac{3}{4}* frac{5}{7}= frac{5*3}{4*7}= frac{15}{28};$
$frac{1}{8}* frac{3}{4}= frac{1*3}{8*4}= frac{3}{32};$
$frac{4}{7} *frac{5}{6}=frac{4*5}{7*6}=frac{20}{42};$
$frac{2}{5}* frac{7}{11}=frac{2*7}{5*11}=frac{14}{55};$
$frac{1}{2} *frac{4}{9}=frac{1*4}{2*9}=frac{4}{18}=frac{2}{9};$
$frac{11}{12}* frac{8}{9}=frac{11*8}{12*9}=frac{11*2}{3*9}=frac{22}{27};$
$frac{2}{5}*frac{3}{2}=frac{2*3}{5*2}=frac{3}{5};$
$frac{11}{15}*frac{3}{5}=frac{11*3}{15*5}=frac{11}{5*5}= frac{11}{25};$
$frac{15}{16}*frac{5}{9}=frac{15*5}{16*9}=frac{5*5}{16*3}=frac{25}{48};$
$frac{12}{25}*frac{9}{16}=frac{12*9}{25*16}=frac{3*9}{25*4}=frac{27}{100};$
$frac{14}{17}*frac{34}{63}=frac{14*34}{17*63}=frac{2*2}{1*9}= frac{4}{9};$
$frac{17}{26}*frac{13}{18}=frac{17*13}{26*18}=frac{17*1}{2*18}=frac{17}{36};$
$(frac{4}{5})^2=frac{4}{5}*frac{4}{5}=frac{4*4}{5*5}=frac{16}{25};$
$(frac{2}{3} )^3=frac{2}{3}* frac{2}{3}*frac{2}{3}=frac{2*2*2}{3*3*3}=frac{8}{27};$
$( frac{1}{7} )^2= frac{1}{7}* frac{1}{7}= frac{1*1}{7*7}= frac{1}{49};$
