Question

Помогите решить пожалуйста И объясните как это делать

Answer 1

Подробное решение:

а)

$2 - \frac{1}{4} = \frac{8}{4} - \frac{1}{4} = \frac{8 - 1}{4} = \frac{7}{4} = 1 \frac{3}{4}$

б)

$7 - \frac{5}{12} = \frac{84}{12} - \frac{5}{12} = \frac{84 - 5}{12} = \frac{79}{12} = 6 \frac{7}{12}$

в)

$8 - 2 \frac{1}{7} = \frac{56}{7} - \frac{15}{7} = \frac{56 - 15}{7} = \frac{41}{7} = 5 \frac{6}{7}$

г)

$4 - 3 \frac{5}{9} = \frac{36}{9} - \frac{32}{9} = \frac{36 - 32}{9} = \frac{4}{9}$

д)

$3 \frac{1}{5} - 1 \frac{4}{5} = \frac{16}{5} - \frac{9}{5} = \frac{16 - 9}{5} = \frac{7}{5} = 1 \frac{2}{5}$

е)

$6 \frac{1}{8} - 2 \frac{3}{8} = \frac{49}{8} - \frac{19}{8} = \frac{49 - 19}{8} = \frac{30}{8} = \frac{15}{4} =3 \frac{3}{4}$

ж)

$4 \frac{5}{11} - 3 \frac{9}{11} = \frac{49}{11} - \frac{42}{11} = \frac{49 - 42}{11} = \frac{7}{11}$

з)

$8 \frac{4}{13} - 5 \frac{8}{13} = \frac{108}{13} - \frac{73}{13} = \frac{108 - 73}{13} = \frac{35}{13} = 2 \frac{9}{13}$
