Proszę o szybką pomoc!!! Daję naj! :) a) (-100)*8/125 = b) (-3,6)*4/9 = c) -7/8 : (-5,6) = POTRZEBNE NA TERAZ!!!

a) (-100)*8/125 = - 4 * 8/5 = - 32/25 = - 1 7/25 b) (-3,6)*4/9 = - 18/5 * 4/9 = - 72/45 = - 1 27/45 = - 1 3/5 c) -7/8 : (-5,6) = - 7/8 : (- 28/5) = - 7/8 * (- 5/28) = - 1/8 * (- 5/4) = 5/32

[latex]-100*frac{8}{125}=-frac{100}{1}*frac{8}{125}=-frac{800}{125}=-6frac{2}{5}\\b)\(-3,6)*frac{4}{9}=-frac{36}{10}*frac{4}{9}=-frac{8}{5}=-1frac{3}{5}\\c)\-frac{7}{8}:(-5,6)=-frac{7}{8}:(-frac{56}{10})=-frac{7}{8}*(-frac{10}{56})= frac{5}{32}[/latex]
