Question

Cate numero naturale sunt situate pe axa numerica intre 3 intregi 2/7 si 15 intregi 15/23 ?
Determinati aceste numere.

Answer 1

$3 \frac{2}{7} = \frac{3 \times 7 + 2}{7} = \frac{21 + 2}{7} = \frac{23}{7} = 3.28$

$15 \frac{15}{23} = \frac{15 \times 23 + 15}{23} = \frac{345 + 15}{23} = \frac{360}{23}$

$= 15.65$

Numerele sunt:4,5,6,7,8,9,10,11,12,13,14,15.

Answer 2

= (3x7+2)/7 |. (15x23+15 )/23
= 23/7 |. 360/23

360:23 - 23:7 = 15,65 - 3,28
= 12,4
Deci 12 număr !

23:7 = 3,28
{4,5,6,7,8,9,10,11,12,13,14,15}
