OPERACIONES CON FRACCIONES

1. [(5/5) + (20/2)] –[(1/2) + (5/2)] = (11) – (3) = _8_ = 4
6 (9/3) 18 18 9

Solución:

[(5/5) + (20/2)] = 10 + 100 = 110 = 1110 10

[(1/2) + (5/2)] = 2 + 10 = 12 = 3
4 4

6 (9/3) = (6/1) x (9/3)= 54/3 = 18

2. [(90/3) - (100/5)] + [(6/2) x (3/1)] = (10) + (9) = _(19/1) _ = 342
[(7/4) / (9/2)] (14/36) (14/36) 7Solución:

[(90/3) - (100/5)] = 450 - 300 = 150 = 10
15 15

[(6/2) x (3/1)] = 6 x 3 = 18 = 9
2x 1 2

[(7/4) / (9/2)] = (7/4) x (2/9) = 14/36
[(19/1) / (14/36)] = (19/1) x (36/14) = 684 /14 = 342/7Segunda

3. [(6/4) x (8/5)] + [(1/2) - (4/7)] + [(3/2) x (9/3)] = 239/35

Solución:
[(6/4) x (8/5)] = 48/20
[(1/2) - (4/7)] = (7- 8)/14 = -1/14[(3/2) x (9/3)] = 27/6

= [48/20] + [-1/14] + [27/6] = [(1008) + (-30) + (1890)] / 420 = 2868/420
