\(15.360+150.2.27+1500\)

\(=150\left(36+54+10\right)\)

\(=150.100=15000\)

15.360+150.2.27+1500

=150.36 +150.54 +150.10

=150.(36+54+10)

=150.100

=15000

15.360+150.2.27+1500

=15.36.10+150.54+150.10

=150.36+150.54+150.10

=150.(36+54+10)

=150.100

=15000

cứ chép thế ko cần hiểu

15 . 360 + 150 . 2 . 27 + 1500

= 15 . ( 10 . 36 ) + 150 . ( 2 . 27 ) + 150 . 10

= 15 . 10 . 36 + 150 . 54 + 150 . 10

= 150 . 36 + 150 . 54 + 150 . 10

= 150 . ( 36 + 54 + 10 )

= 150 . 100

= 15 000  

2.17.9+18.540+29.18

=18.17+18.540+29.18

=18(17+540+18)

=18.575

(đề sai hay sao hả)

bạn trả lời hết giúp mk đc ko

= 1500 : 25 - 1500 : 1 + 1500 : 76

= 1500 : ( 25 - 1 + 76 )

=1500 : 100

= 15

Tick nha

= 1500 : 25 - 1500 : 1 + 1500 : 76

= 1500 : ( 25 - 1 + 76 )

=1500 : 100

= 15

1500+(-1500)=0

1500 + ( -1500 )

= 0

1400 Nha bn

1500+1500=1600+1400

1500:10+1500:90

=1500: (10 + 90 )

= 1500 : 100

= 15

k mình nha

1500:10+1500:90

=1500:(10+90)

=1500:100

=15

x +1500=1500 +500

x +1500=2000

  x =2000-1500

  x =500 ai k mk mk k lai sieu hua

x + 1500 = 1500 + 500

x + 1500 = 2000

x             = 2000 - 1500

x             = 500        

a)\(1500+450\div2,5-15\)

\(=\)\(1500+180-15\)

\(=1680-15\)

\(=1665\)

b)\(1500+4,5\div25-1,5\)

\(=1500+0,18-1,5\)

\(=1500,18-1,5\)

\(=1498,68\)

c)\(1500+4,6\div2,5-15\)

\(=1500+1,84-15\)

\(=1501,84-15\)

\(=1486,84\)

1486,84 nhé bạn
