ТУТ ЕСТЬ ПРИМЕР КАК НАДО РЕШАТЬ КАТОРЫЕ ЗАЧЕРКНУТЫЕ НЕ НАДО ! 3 ПРИМЕРА

Answer 1

3.

$6 \frac{5}{9} \div 6 \frac{4}{19} = \frac{59}{9} \div \frac{118}{19} = \\ = \frac{59 \times 19}{9 \times 118} = \frac{19}{9 \times 2} = \frac{19}{18} = 1 \frac{1}{18}$

4.

$5 \frac{3}{7} \div 7 \frac{1}{8} = \frac{38}{7} \div \frac{57}{8} = \\ = \frac{38 \times 8}{7 \times 57} = \frac{2 \times 8}{7 \times 3} = \frac{16}{21}$

5.

$4 \frac{8}{15} \div 1 \frac{9}{25} = \frac{68}{15} \div \frac{34}{25} = \\ = \frac{68 \times 25}{15 \times 34} = \frac{2 \times 5}{3} = \frac{10}{3} = 3 \frac{1}{3}$

6.

$1 \frac{13}{15} \div 1 \frac{3}{5} = \ \frac{28}{15} \div \frac{8}{5} = \\ = \frac{28 \times 5}{15 \times 8} = \frac{7 \times 1}{ 3\times 2} = \frac{7}{6} = 1 \frac{1}{6}$
