OPERACION
1) 7+ 10.8 + 6 :3 =
2) 5 (18-11).+ 18: 9 =
3) 18 : 6 + 42-5.3=
4) 7.8- (125 - 34) =
5) 18 - 15 + 25 = 5.6 =​

Answer 1

Explicación paso a paso:

OPERACION:

$7 + 10 \times 8 + 6 \div 3 \\ 7 + 80 + 2 \\ 87 + 2 \\ 89$

$5 \times (18 - 11) + 18 \div 9 \\ 5 \times 7 + 2 \\ 35 + 2 \\ 37$

$18 \div 6 + 42 - 5 \times 3 \\ 3 + 42 - 15 \\ 45 - 15 \\ 30$

$7 \times 8 - (125 - 34) \\ 56 - 91 \\ - 35$

$18 - 15 + 25 = 5 \times 6 \\ 3 + 25 = 30 \\ 28 = 30$
