Выполним вычитание. а) 3 - $$\frac{1}{4}$$ =2$$\frac{4}{4}$$ - $$\frac{1}{4}$$ =2$$\frac{3}{4} \( 3 - \frac{1}{4} = 2\frac{4}{4} - \frac{1}{4} = 2\frac{3}{4} \) б) 2 - $$\frac{1}{3}$$ = 1$$\frac{3}{3}$$ - $$\frac{1}{3}$$ = 1$$\frac{2}{3}$$ \( 2 - \frac{1}{3} = 1\frac{3}{3} - \frac{1}{3} = 1\frac{2}{3} \) в) 5 -$$\frac{3}{4}$$ = 4$$\frac{4}{4}$$ - $$\frac{3}{4}$$ = 4$$\frac{1}{4}$$ \( 5 - \frac{3}{4} = 4\frac{4}{4} - \frac{3}{4} = 4\frac{1}{4} \) г) 10 -$$\frac{2}{9}$$ = 9$$\frac{9}{9}$$ - $$\frac{2}{9}$$ = 9$$\frac{7}{9}$$ \( 10 - \frac{2}{9} = 9\frac{9}{9} - \frac{2}{9} = 9\frac{7}{9} \) д) 11 -$$\frac{11}{100}$$ = 10$$\frac{100}{100}$$ - $$\frac{11}{100}$$ = 10$$\frac{89}{100}$$ \( 11 - \frac{11}{100} = 10\frac{100}{100} - \frac{11}{100} = 10\frac{89}{100} \) е) 5 -$$\frac{2}{7}$$ = 4$$\frac{7}{7}$$ - $$\frac{2}{7}$$ = 4$$\frac{5}{7}$$ \( 5 - \frac{2}{7} = 4\frac{7}{7} - \frac{2}{7} = 4\frac{5}{7} \) ж) 13 -$$\frac{7}{10}$$ = 12$$\frac{10}{10}$$ - $$\frac{7}{10}$$ = 12$$\frac{3}{10}$$ \( 13 - \frac{7}{10} = 12\frac{10}{10} - \frac{7}{10} = 12\frac{3}{10} \) з) 1 -$$\frac{2}{5}$$ = $$\frac{5}{5}$$ - $$\frac{2}{5}$$ = $$\frac{3}{5}$$ \( 1 - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{3}{5} \)
