Answer 2

Explicação passo-a-passo:

1) 18,5 + 15 + 36,8 = 70.3

2) 86.5 + 12.5 = 99

3) Antônio > 15 +29 = 44

Sua tia > 15*3+29= 74

4) (25,5 + 17,5 + 9,6) *2 = 105,2

5) 15 +(15+35)+(15+35+6)

15+50+56

121

6)19, 38, 76, 152, 304

7)138,5+112+12,6+30+111,4+117,50= 404.5

8) (9*12)+(4*10)+(2*100+5*1)

108+40+205

353

9) 2176-1739= 437
