bài 1: tính

4000x30:15000 = 

15000:10x8 =

15x6:3 =

75000:5000x15 =

2000000:4x4 =

9x15:90 =

9x6:8 =

11000:5500x12 =

Answer 1

=8

=12000

=30

=225

=2000000

=1,5

= 6,75

=24

Answer 2

4000 x 30 : 15000 = 120000 : 15000 = 8

15000 : 10 x 8 = 1500 x 8 = 12000

15 x 6 : 3 = 90 : 3 = 30

75000 : 5000 x 15 = 15 x 15 = 225

2000000 : 4 x 4 = 500000 x 4 = 2000000

9 x 15 : 90 = 135 : 90 = 1,5

9 x 6 : 8 = 54 : 8 = 6, 75

11000 : 5500 x 12 = 2 x 12 = 24

Answer 3

4000x30:15000=12000:15000=0,8

15000:10x8=1500x8=12000

15x6:3=90:3=3

75000:5000x15=15x15=225

500000x4=2000000

9x15:90=135:90=1.5
