Question

1. Oblicz według wzoru.
1/3x + 0,5x= (1/3+0,5) x=(2/6 + 3/6 ) x=5/6x
a) 4/3 + 5/8x=
b) 1,2x+ 2/3x=
c)1/4x+5/6x-1/2x=
d)3/7x-0,2x+x=

Answer 1

a) 4/3 + 5/8x= (4/3+5/8) x=(32/24 +15/24) x=47/24x=1 i 23/24x
b) 1.2x +2/3x=(1.2 +2/3) x=( 36/30 + 20/30) x=56/30=1 i 26/30x
c) 1/4x +5/6x -1/2x = (1/4 +5/6 -1/2) x= (3/12+10/12-6/12)x=7/12x
d) 3/7x -0.2x+2x= (3/7-0.2+2)x=(30/70 -20/70 +10/10)x=20/70x
