13 x 9 = ...........
43 x 14 = .......
805: 7 = ...........
249: 3= ............vă rog dau coroana ​

Answer 1

Răspuns:

$286 + 42.118 = 42.404$

$p = > 42.404 - 42.118 = 286$

$28.559 - 4.389 = 24.170$

$p = > 24.170 + 4.389 = 28.559$

$13 \times 9 = 117$

$p = > 117 \div 9 = 13$

$43 \times 14 = 602$

$p = > 602 \div 14 = 43$

$805 \div 7 = 115$

$p = > 115 \times 7 = 805$

$249 \div 3 = 83$

$p = > 83 \times 3 = 249$
