Answer 1

Odpowiedź:

a)

4/3x + 5/8x = (4/3 + 5/8)x = (1 1/3 + 5/8)x = (1 8/24 + 15/24)x = 1 23/24x

b)

1,2x + 2/3x = (1,2 + 2/3)x = (1 1/5 + 2/3)x = (1 3/15 + 10/15)x = 1 13/15x

c)

1/4x + 5/6x - 1/2x = (1/4 + 5/6 - 1/2)x = (1/4 + 5/6 - 3/6)x = (1/4 + 2/6)x =

= (1/4 + 1/3)x = (3/12 + 4/12)x = 7/12x

d)

3/7x - 0,2x + x = (3/7 - 1/5 + 1)x = (15/35 - 7/35 + 1)x = 1 8/35x
