Answer 2

PRIMERA ACTIVIDAD

(x) (7/15) = 1/3

(7x/15) = 1/3

15 (7x/15) = 15 (1/3)

7x = 5

x = 5/7

SEGUNDA ACTIVIDAD

(x) (5/9) = 2/3

(5x/9) = 2/3

9 (5x/9) = 9 (2/3)

5x = 6

x = 6/5

TERCERA ACTIVIDAD

(x) (8/3) = 5/3

(8x/3) = 5/3

3 (8x/3) = 3 (5/3)

8x = 5

x = 5/8

CUARTA ACTIVIDAD

(x) (13/20) = 1/4

(13x/20) = 1/4

20 (13x/20) = 20 (1/4)

13x = 5

x = 5/13

QUINTA ACTIVIDAD

(x) (3/5) = 3/4

(3x/5) = 3/4

20 (3x/5) = 20 (3/4)

12x = 15

x = 15/12

SEXTA ACTIVIDAD

(5/36) (x) = 1/6

(5x/36) = 1/6

36 (5x/36) = 36 (1/6)

5x = 6

x = 6/5

SÉPTIMA ACTIVIDAD

(7/3) (x) = 3

(7x/3) = 3

3 (7x/3) = 3 (3)

7x = 9

x = 9/7

OCTAVA ACTIVIDAD

(10/25) (x) = 3/2

(10x/25) = 3/2

50 (10x/25) = 50 (3/2)

20x = 75

x = 75/20

x = 15/4

NOVENA ACTIVIDAD

(5/12) (x) = 1/2

(5x/12) = 1/2

12 (5x/12) = 12 (1/2)

5x = 6

x = 6/5

DÉCIMA ACTIVIDAD

(2/5) (x) = 8/3

(2x/5) = 8/3

15 (2x/5) = 15 (8/3)

6x = 40

x = 40/6

x = 20/3
