Question

30/7:25/14+2  1/3·3/14



explicati.mi cum se fac va implorrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

Answer 1

30/7x14/25+21/3x3/14
12/5+3/2=12x2+3x5/10=24+15/10=39/10=3,9

Answer 2

$\frac{30}{7} * \frac{14}{25}+ \frac{21}{3}* \frac{3}{14}$

Acum vom simplifica 7 cu 14 si ramane 2, 30 cu 25 si ramane 6 si 5
iar la cea de-a doua inmultire simplificam 3 cu 3 si 21 cu 14 si ramane 3 si 2

Dupa simplificari vom avea 12/5+3/2 torul comun va fi 10
24+15/10=39/10=3.9
