Answer 1

Respuesta:

Explicación paso a paso:

a) 26:2+(32-15:3+2.3)+18:3=

=13+32− 15 /3 +2.3+ 18 /3

=13+32−5+2.3+ 18 /3

=13+27+2.3+ 18 /3

=13+29.3+ 18 /3

=42.3+ 18 /3

=42.3+6

=48.3

b) 7+23-28:7+(62+15.4):2=

=30− 28 /7 + 62+15.4 /2

=30−4+ 62+15.4 /2

=26+ 62+15.4 /2

=26+ 77.4 /2

=26+38.7

=64.7

c) (12-9:3+52+1):7-(43-72):5=

= 12−3+52+1 /7 −( 43−72 /5 )

= 9+52+1 /7 −( 43−72 /5 )

= 61+1 /7 −( 43−72 /5)

=62 /7 −( 43−72 /5 )

= 62 /7 −( −29 /5 )

= 513 /35

d) (102:2-33+7):6+(92-82+32):2=

= 51−33+7 /6 + 92−82+32 /2

= 18+7 /6 + 92−82+32 /2

= 25 /6 /+ 92−82+32 /2

= 25 /6 + 10+32 /2

= 25 /6 + 42 /2

= 25 /6 +21

= 151 /6

e) +92:32-(24+ -5.4+ )=

f) +(24:6+72-24-62)=

=4+72−24−62

=76−24−62

=52−62

=−10

g) 70:2-1+63): =

=35−1+63

=34+63

=97

Listooo!
