1a) 35,88 +19,36=55,24                                   b) 8,32 + 14,6 + 5,24= 28,16

    81,625 + 147,307= 228,932                           8,9 + 9,3 + 4,7 + 5= 27,9

    539,6 +73,495= 613,095                             324,8 + 66,7 + 208,4= 599,9

    247,06 + 316,492= 563,552                           24,9 + 57,36 + 5,45= 87,71

2,a) 25,7 + 9,48 +14,3= (25,7+14,3) + 9,48= 40+9,48= 49,48                         b) 8,65 + 7,6 + 1,35 + 0,4= (8,65+ 1,35) + (7,6+0,4)= 10+8= 18
