Question

(4-14/33*1.1/21)*5.5/8=

Answer 1

Пошаговое объяснение:

(4-14/33×1 1/21)×5 5/8=20

1) 14/33×1 1/21=14/33×22/21=2/3×2/3=4/9

2) 4-4/9=36/9-4/9=32/9

3) 32/9×5 5/8=32/9×45/8=4/1×5/1=20

Answer 2

$( 4 - \frac{14}{33} \times 1 \frac{1}{21} ) \times 5 \frac{5}{8} = 20$

$1) \frac{14}{33} \times 1 \frac{1}{21} = \frac{14}{33} \times \frac{22}{21} = \frac{2}{3} \times \frac{2}{3} = \frac{4}{9}$

$2)4 - \frac{4}{9} = \frac{36}{9} - \frac{4}{9} = \frac{32}{9}$

$3) \frac{32}{9} \times 5 \frac{5}{8} = \frac{32}{9} \times \frac{45}{8} = \frac{4}{1} \times \frac{5}{1} = 20$
