Answer 1

a) 3500:2=1750
6400:2=3200
550:2=275


b)1260:3=420
642:3=214
15.600:3=5200



c)4800:4=1200
32400:4=8100
640:4=160

Answer 2

a)
$\frac{1}{2} \times 3500 = 1750 \: lei$
$\frac{1}{2} \times 6400 = 3200 \: kg$
$\frac{1}{2} \times 550 = 275 \: m$
b)
$\frac{1}{3} \times 1260 = 420 \: km$
$\frac{1}{3} \times 642 = 214 \: kg$
$\frac{1}{3} \times 15600 = 5200 \: lei$
c)
$\frac{1}{4} \times 4800 = 1200 \: kg$
$\frac{1}{4} \times 32400 = 8100 \: lei$
$\frac{1}{4} \times 640 = 160 \: km$
