C. 22/42 , - 4/14 , -8/30 , 14/18
D. 39/21 , 75/24 , 27/15 , 9/12

Answer 1

El orden para cada lista es:

• 1/2, 3/5, 2 1/3, 2 1/3
• 10/10, 13/10, 2 1/5, 2 5/6
• -4/14, -8/30, 22/42, 14/18
• 9/12, 27/15, 39/21, 75/24

Llevamos los números de cada lista: a números con igual denominador, de manera q la mayor sera la que tenga mayor numerados

A. 3/5 , 2 1/3 , 2 2/3 , 1/2

• 3/5 = 18/30
• 2 1/3 = 2 + 1/3 = 7/3 = 70/30
• 2 2/3 = 2 + 2/3 = 8/3 = 80/30
• 1/2 = 15/30

Ordenados: 15/30, 18/30, 70/30, 80/30 = 1/2, 3/5, 2 1/3, 2 1/3

B. 2 5/6 , 13/10 , 2 1/5 , 10/10

• 2 5/6 = 2 + 5/6 = 17/6 = 85/30
• 13/10 = 39/30
• 2 1/5 = 2 + 1/5 = 11/5 = 66/30
• 10/10 = 30/30

Ordenados: 30/30, 39/30, 66/30, 85/30 = 10/10, 13/10, 2 1/5, 2 5/6

C. 22/42 , - 4/14 , -8/30 , 14/18

• 22/42 = 330/630
• -4/14 = -180/630
• -8/30 = -168/630
• 14/18= 490/630

Ordenados: -180/630, -168/630, 330/630, 490/630 = -4/14, -8/30, 22/42, 14/18

D. 39/21 , 75/24 , 27/15 , 9/12

• 39/21 = 1560/840
• 75/24 = 2625/840
• 27/15 = 1512/840
• 9/12 = 630/840

Ordenados: 630/840, 1512/630, 1560/630, 2625/630 = 9/12, 27/15, 39/21, 75/24
