Answer 1

Resolviendo los problemas:

a) 3/4 - 1/2 = 1/4

3/4 - 1/2 = (3*2 - 4*1)/(4*2)

3/4 - 1/2 = (6 - 4)/(8)

3/4 - 1/2 = 2/8

3/4 - 1/2 = 1/4

b) 2/4 - 1/3 = 1/6

2/4 - 1/3 = (2*3 - 4*1)/(4*3)

2/4 - 1/3 = (6 - 4)/(12)

2/4 - 1/3 = 2/12

2/4 - 1/3 = 1/6

c) 5/9 - 1/4 = 11/36

5/9 - 1/4 = (5*4 - 9*1)/(9*4)

5/9 - 1/4 = (20 - 9)/(36)

5/9 - 1/4 = 11/36

d) 3/5 - 1/2 = 1/10

3/5 - 1/2 = (2*3 - 5*1)/(5*2)

3/5 - 1/2 = (6 - 5)/(10)

3/5 - 1/2= 1/10

e) 4/7 + 3/5 = 41/35

4/7 + 3/5 = (4*5 + 7*3)/(7*5)

4/7 + 3/5 = (20 + 21)/(35)

4/7 + 3/5 = 41/35

f) 2/3 + 4/9 = 2/9

2/3 + 4/9 = (2*9 + 3*4)/(3*9)

2/3 + 4/9 = (18 + 12)/(27)

2/3 + 4/9 = 30/27

2/3 + 4/9 = 10/9
