Question

$6x \div 3 \frac{1}{3} = 2.4 \div \frac{1}{12}$
$1 \frac{1}{9} \div x = 2 \frac{2}{3} \div 3 \frac{3}{5}$
$\frac{1.25}{y + 2.4}= \frac{0.6}{2.4}$
Помогите пожалуйста ​

Пошаговое объяснение:

6x : 3 1/3 = 2 4/10 : 1/12

6x : 10/3 = 2 2/5 * 12/1

6x : 10/3 = 12/5 * 12/1

6x : 10/3 = 144/5

6x = 144/5 * 10/3

6x = 48/1 * 2/1

6x = 96

x = 96 : 6

x = 16

1 1/9 : x = 8/3 : 18/5

10/9 : x = 8/3 * 5/18

10/9 : x = 40/54

10/9 : x = 20/27

x = 10/9 : 20/27

x = 10/9 * 27/20

x = 1/1 * 3/2

x = 3/2

x = 1 1/2

y + 2,4 = 1,25*2,4 / 0,6

y + 2,4 = 3/0,6

y + 2,4 = 5

y = 5 - 2,4

y = 2,6
