Por amplificación.

Multiplicas numerador y denominador por un mismo número.

2/5
2/5 * 2/2 =
(2 * 2)/(5 * 2) =
4/10
2/5 = 4/10

- 1/7 * 3/3 =
(- 1 * 3)/(7 * 3) =
- 3/21
- 1/7 = - 3/21

2/3 * 5/5 =
(2 * 5)/(3 * 5) =
10/15
2/3 = 10/15


9/5
9/5 * 2/2 =
(9 * 2)/(5 * 2) =
18/10
9/5 = 18/10

- 3/2
- 3/2 * 10/10 =
(- 3 * 10)/(2 * 10) =
- 30/20
- 3/2 = - 30/20

Answer 2

Respuesta:

2/5 = 4/10 = 8/20 = 16/40

1/7 = 2/14 = 4/28 = 8/56

2/3 = 4/6 = 8/12 = 16/24

9/5 = 18/10 = 36/20 = 72/40

3/2 = 6/4 = 12/8 = 24/16
