Witaj :) [latex]2 frac{3}{4} - 1 frac{2}{4} = frac{11}{4} - frac{6}{4} = frac{5}{4} [/latex] [latex]= 1 frac{1}{4} [/latex] [latex]= 1,25[/latex] [latex]7 frac{3}{8} - 2 frac{4}{8} = frac{59}{8} - frac{20}{8} = frac{39}{8} = 4 frac{7}{8} [/latex] [latex]= 4,875[/latex] [latex]4 frac{1}{2} -3 frac{1}{2} = frac{9}{2} - frac{7}{2} = frac{2}{2} = 1[/latex] [latex]6 - 2 frac{2}{8} = frac{6}{1} - frac{18}{8} = frac{48}{8} - frac{18}{8} = frac{30}{8} = frac{15}{4} = 3 frac{3}{4} = 3,75[/latex] [latex]2 frac{2}{8} - 3 = frac{18}{8} - frac{3}{1} = frac{18}{8} - frac{24}{8} = - frac{6}{8} = - frac{3}{4} = -0,75[/latex] [latex]3 * 8 frac{4}{8} = 3 * frac{68}{8} = frac{3}{1} * frac{68}{8} = frac{204}{8} = frac{102}{4} = 25 frac{2}{4} = 25,5[/latex] [latex]4 * 3 frac{6}{5} = frac{4}{1} * frac{21}{5} = frac{84}{5} = 16 frac{4}{5} = 16,8[/latex] [latex]8 frac{3}{2} * 5 frac{4}{2} = frac{19}{2} * frac{14}{2} = frac{19}{1} * frac{7}{2} = frac{133}{2} = 66 frac{1}{2} = 66,5[/latex] [latex]7 frac{4}{8} * 2 = frac{60}{8} * frac{2}{1} = frac{60}{4} * frac{1}{1} = frac{60}{4} =15[/latex] Mam nadzieję, że pomogłam.
