=1+1/3-1/4+1/4-1/5+1/5-1/6

=4/3-1/6

=8/6-1/6=7/6

Logic qué

=7/6

12,12 x 7,5 + 12,12 : 2 + 12,12 + 12,12

= 12,12 x 7,5 + 12,12 x 0,5 + 12,12 x 1 + 12,12 x 1

= 12,12 x (7,5 + 0,5 + 1 + 1)

= 12,12 x 10

= 121,2

121,2 nha bạn

File: undefined 

giúp mình với

96

a. ( 20,48 + 11,52 ) : 3,2 

= 32 : 3,2 = 10 

b. ( 2,5 x 4 ) x 16,7 

= 10 x 16,7 

= 167

bạn kia thiếu số 2 ở 16,27=16,7 kìa

124 x 25 + 24 x 124 + 50 + 124

= 124 x 25 + 50 ( 24 + 1 )

= 124 x ( 25 + 50 + 25 )

= 124 x 100

= 124000

Nhìn mà mún lòi cả con mắt hà

kết quả là 30.

(10,35 + 11,27 + 16,54) - ( 0,35 + 6,54 + 1,27)

= 10,35 + 11,27 + 16,54 - 0,35 - 6,54 - 1,27

=( 10,35 - 0,35)+(11,27 - 1,27) +(16,54 - 6,54)

= 10 + 10 + 10

= 30

he,s lô hê,s li li

58 x 58 + 52 x 58 - 10

= 58 x ( 58 + 52 ) - 10

= 58 x 110 - 10

= 6380 - 10

= 6370

58x 58+52×58-10

=58x (52+58)-10

 =58x110-10

=6380-10

=6370

58 x 58 + 52 x 58 - 10

= 58x ( 58+52) - 10

= 58 x 110 - 10

= 6380-10

=6370

\(2367\times4\times25\\ =2367\times\left(4\times25\right)\\ =2367\times100\\ =236700\)

2367 x 4 x 25

= 2367 x 100=236700

2367 x 4 x 25

= 2367 x 100=236700
