Question

6 задание второй пункт

Answer 1

Ответ:

1)

$2 \frac{5}{9} + 5 \frac{1}{3} = 7 \frac{5 + 3}{9} = 7 \frac{8}{9}$

2)

$\frac{5}{6} \div 3 \frac{1}{3} = \frac{5}{6} \times \frac{3}{10} = \frac{1}{4}$

3)

$7 \frac{8}{9} \times 18 = 7 \frac{8}{9} \times \frac{18}{1} = \frac{71}{9} \times \frac{18}{1} = \frac{142}{1} = 142$

4)

$5.2 \times \frac{1}{6} = 5 \frac{2}{10} \times \frac{1}{6} = \frac{51}{10} \times \frac{1}{3} = \frac{51}{30} = 1 \frac{21}{30}$

5)

$142 + \frac{1}{4} = \frac{568}{4} + \frac{1}{4} = \frac{143}{4} = 35 \frac{3}{4}$

6)

$35 \frac{3}{4} - 1 \frac{21}{30} = 34 \frac{12 - 22}{60} = 33 \frac{72 - 22}{60} = 33 \frac{50}{60} = 33 \frac{25}{30} = 33 \frac{5}{6}$

ответ:

$33 \frac{5}{6}$
