Hola monserratek735!!

Explicación paso a paso:

1ra Operación:

$45 - 7 + 10 - 32 + 5 - 7 = \\ \\ 38 + 10 - 32 + 5 - 7 = \\ \\ 48 - 32 + 5 - 7 = \\ \\ 16 + 5 - 7 = \\ \\ 21 - 7 = \\ \\ 14$

2da Operación:

$7 + 9 \div 3 + 8 \times 4 + 15 + 20 \div 5 = \\ \\ 7 + 3 + 8 \times 4 + 15 + 20 \div 5 = \\ \\ 10 + 8 \times 4 + 15 + 20 \div 5 = \\ \\ 10 + 32 + 15 + 20 \div 5 = \\ \\ 42 + 15 + 20 \div 5 = \\ \\ 57 + 20 \div 5 = \\ \\ 54 + 4 = \\ \\ 61$

3ra Operación:

$45 \div 9 + 7 - 9 + 6 \times 8 + 69 \div 3 - 6 = \\ \\ 5 + 7 - 9 + 6 \times 8 + 69 \div 3 - 6 = \\ \\ 12 - 9 + 6 \times 8 + 69 \div 3 - 6 = \\ \\ 3 + 6 \times 8 + 69 \div 3 - 6 = \\ \\3 + 48 + 69 \div 3 - 6 = \\ \\ 51 + 69 \div 3 - 6 = \\ \\ 51 + 23 - 6 = \\ \\ 74 - 6 = \\ \\ 68$

4ta Operación:

$9 + 30 - (7 + 5 \times 4) + (5 + 30 \div 6 + 12) = \\ \\ 39 - (7 + 5 \times 4) + (5 + 30 \div 6 + 12) = \\ \\ 39 - (7 + 20) + (5 + 30 \div 6 + 12) = \\ \\ 39 - 27 + (5 + 30 \div + 12) = \\ \\ 12 + 5 + 30 \div 6 + 12 = \\ \\ 17 + 30 \div 6 + 12 = \\ \\ 17 + 5 + 12 = \\ \\ 22 + 12 = \\ \\ 34$

Answer 2

Respuesta:

a) 15 + 7 - 7 - 9 + 54 -7 = 53

b) 45 - 7 + 10 - 32 + 5 - 7 = 14

c) 6 + 7 + (8 + 7 - 5) + 40 - 18 = 45

d) (6 + 45 + 12 - 8) - (4 + 20 + 56 - 30) = 5

e) 7 + 9 ÷ 3 + 8 × 4 + 15 + 20 ÷ 5 = 61

f) 45 ÷ 9 + 7 - 9 + 6 × 8 + 69 ÷ 3 - 6 = 68

g) 9 + 30 - (7 + 5 × 4) + (5 + 30 ÷ 6 + 12) = 34

h) 8 + (6 × 3 + 5) - (56 ÷ 7 - 5) × 8 = 7

     

paso a paso:

a) 15 + 7 - 7 - 9 + 54 -7

= 15 - 9 + 47

= 6 + 47

= 53  

b) 45 - 7 + 10 - 32 + 5 - 7

= 38 - 22 - 2

= 38 -24

= 14  

c) 6 + 7 + (8 + 7 - 5) + 40 - 18

= 6 + 7 + 10 + 40 - 18

= 13 + 50 - 18

= 13 + 32

= 45  

d) (6 + 45 + 12 - 8) - (4 + 20 + 56 - 30)

= 55 - 50

= 5  

e) 7 + (9 ÷ 3) + (8 × 4) + 15 + (20 ÷ 5)

= 7 + 3 + 32 + 15 + 4

= 10 + 32 + 19

= 42 + 19

= 61  

f) (45 ÷ 9) + 7 - 9 + (6 × 8) + (69 ÷ 3) - 6

= 5 + 7 - 9 + 48 + 23 - 6

= 12 + 39 + 17

= 41 + 17

= 68  

g) 9 + 30 - (7 + 5 × 4) + (5 + 30 ÷ 6 + 12)

= 39 - (7 + 20) + (5 + 5 + 12)

= 39 - 27 + 22

= 34

h) 8 + (6 × 3 + 5) - (56 ÷ 7 - 5) × 8

= 8 + (18 + 5) - (8 - 5) × 8

= 8 + 23 - 3 × 8

= 31 - 24

= 7
