Answer 1

Ответ:

1)

А)

$6 \frac{4}{9} \times 27 = \frac{58}{9} \times \frac{27}{1} = \frac{58}{1} \times 3 = 58 \times 3 = 174$

Б)

$5 \frac{5}{9} \times \frac{45}{1} = \frac{50}{9} \times \frac{45}{1} = \frac{50}{1} \times \frac{9}{1} = 50 \times 9 = 450$

В)

$4 \frac{3}{9} \div \frac{1}{3} = \frac{39}{9} \times \frac{3}{1} = \frac{39}{3} \times \frac{1}{1} = \frac{39}{3} = 13$

Г)

$4 \frac{10}{17} \div \frac{26}{51} = \frac{78}{17} \times \frac{51}{26} = \frac{3}{17} \times 51 = 3 \times 3 = 9$

2)

$x \div 5 \frac{3}{5} = \frac{5}{28} \\ x \div \frac{28}{5} = \frac{5}{28} \\ x = \frac{28}{5} \times \frac{5}{28} = 1$
