Answer 1

Boa noite.

$A) 18-2.4+5= 18 - 8 + 5 = 23 - 8 = 15$

$B) 4.7+5-12= 28 + 5 - 12 = 33 - 12 = 21$

$C)85-4.12-2= 85 - 48 - 2 = 85 - 50 = 35$

$D)23+13.2-9= 23 + 26 - 9 = 49 - 9 = 40$

$E)12.6+8-14= 72 + 8 - 14 = 80 - 14 = 66$

$F)84-5.14+9= 84 - 70 + 9 = 93 - 70 = 23$

$G)42-12+6.9= 42 - 12 + 54 = 96 - 12 = 84$

$H)35-4.5+3= 35 - 20 + 3 = 38 - 20 = 18$

Bons estudos! :-)
