Answer 1

Explicación paso a paso:

1.

1,6+3×(5,6-4,8) =

1,6+ 3(0,8) =

1,6+2,4 =

= 4

2.

2,48-3,1×0,4+2,8×1,7

= 2,48-1,24+4,76

= 7,24-1,24

= 6

3.

4,3-0,2× (0,7+1,2-0,4)

= 4,3-0,2(1,5)

= 4,3-0,3

= 4

4.

4,25-(1,2+0,75)+1,06

= 4,25-1,95+1,06

= 4,25-0,89

= 3,36

5.

5-[8,2-(3,6+1,9-2,4)]

= 5-[8,2-3,1]

= 5-5,1

= -0,1

6.

3,2× 1,1-(4,2÷0,5-3)

= 3,52-8,4+3

= 3,52-5,4

= -1,88

7.

-8,4× 0,1+3×(-4×0,25+3^2)+4,1÷2

= -0,84+3(-1+9)+2,05

-0,84+24+2,05

-0,84+26,05

= 25,21
