Answer 1

Resposta:

a) 603.82.

b) 172.07.

c) 5,128.

d) 17.03.

e) 104.84.

Explicação passo a passo:

a) 0.39 + 0.43 = 0.82, 325 + 278 = 603, 603 + 82 = 603.82.

b) 0.21 - 0.14 = 0.7, 469 - 297 = 172, 172 + 0.7 = 172.7.

c) 0.7 + 0.428 = 1.128, 1 + 3 = 4, 4 + 1.128 = 5,128.

d) 0.002 - 0.99 = -0.97, 23 - 5 = 18, 18 - 0.97 = 17.03.

e) 0.45 + 0.19 = 0.64, 89 + 33 = 112, 112 + 0.64 = 112.64, 112.64 - 7.8 = 104.84.
