va rog e urgent dau coroana​

Answer 1

Răspuns:

map= (2×8+7×3+11×9)/8+3+9=(16+21+99)/20=136/20=34/5

dupa simplificare

map=(3×15+5.2×7+7.25×38)/15+7+38=(45+36.4+275.5)/60=

356.9/60=3569/600

map=(20,(13)*99+2.01(3)*90)/ 99+90 = (1993+181.2)/189=

2174.2/189=

map=(2/5*4+5/6*9+1/3*12)/25= (8/5+15/2+4)/25=(aduci la acelasi numitor) = 131/250
