- Relacion entre dos razones
- a/b = c/d
- Extremos:a y d
Medios: b y c
- Ejemplo:
3/4 = 6/8
3x8 = 4x6
24 = 24
- Ejemplo:
3/4 = 6/8
3x8 = 4x6
24 = 24
- Extremos:a y d
Medios: b y c
- a/b = c/d
- Propiedades
- Propiedad 1
- a+b/b = c+d/d
a-b/b = c-d/d
- Ejemplo:
1/2 = 2/4
- 1+2/2 = 2+4/4
3/2 = 6/4
- 3x4 = 2x6
12 = 12
- 3x4 = 2x6
12 = 12
- 1+2/2 = 2+4/4
3/2 = 6/4
- Ejemplo:
1/2 = 2/4
- a+b/b = c+d/d
a-b/b = c-d/d
- Propiedad 2
- a+b/a = c+d/c
a-b/a = c+d/c
- Ejemplo:
3/4 = 6/8
- 3-4/3 = 6-8/6
-1/3 = -2/6
- (-1)x6 = 3x(-2)
-6 = -6
- (-1)x6 = 3x(-2)
-6 = -6
- 3-4/3 = 6-8/6
-1/3 = -2/6
- Ejemplo:
3/4 = 6/8
- a+b/a = c+d/c
a-b/a = c+d/c
- Propiedad 3
- a+b/a-b =
c+d/c-d
- Ejemplo:
1/2 = 2/4
- 1+2/1-2 = 2+4/2-4
3/-1 = 6/-2
- 3x(-2) = (-1)x6
-6 = -6
- 3x(-2) = (-1)x6
-6 = -6
- 1+2/1-2 = 2+4/2-4
3/-1 = 6/-2
- Ejemplo:
1/2 = 2/4
- a+b/a-b =
c+d/c-d
- Propiedad 4
- a/b = c/d
d/b = c/a
a/c = b/d
- Ejemplo:
1/2 = 3/6
- 1/3 =2/6
6x1 = 3x2
6 = 6
- 6/2 = 3/1
6x1 = 2x3
6 =6
- 6/2 = 3/1
6x1 = 2x3
6 =6
- 1/3 =2/6
6x1 = 3x2
6 = 6
- Ejemplo:
1/2 = 3/6
- a/b = c/d
d/b = c/a
a/c = b/d
- Propiedad 5
- a+-c/b+-d =
a/b = c/d
- Ejemplo:
1/2 = 3/6
- 1+3/2+6 = 4/8
4/8 = 1/2
- 4x2 = 8x1
8 = 8
- 4/8 = 3/6
4x6 = 8x3
24 =24
- 4/8 = 3/6
4x6 = 8x3
24 =24
- 4x2 = 8x1
8 = 8
- 1+3/2+6 = 4/8
4/8 = 1/2
- Ejemplo:
1/2 = 3/6
- a+-c/b+-d =
a/b = c/d
- Propiedad 1
