x- \(\dfrac{1}{2}\) = 6 x \(\dfrac{1}{24}\)

x- 0,5 = 6 x \(\dfrac{1}{24}\)

x- 0,5 = \(\dfrac{1}{4}\) 

x- 0,5 = 0,25

x        = 0,25+0,5

x        =0,3

x - 1/2 = 6 x 1/24 

x - 0,5 = 1/4

x - 0,5 = 0,25 

x = 0,25 + 0,5 

x = 0,3

\(\frac{1}{3}\times\frac{1}{6}\times\frac{1}{9}=\frac{1\times1\times1}{3\times6\times9}=\frac{1}{162}\)

\(\frac{1}{3}\times\frac{1}{6}:\frac{1}{9}=\frac{1}{3}\times\frac{1}{6}\times\frac{9}{1}=\frac{1\times1\times9}{3\times6\times1}=\frac{9}{18}=\frac{1}{2}\)

Tự tính câu cuối đi

\(6\times1=6\)

\(6\times2=12\\ 6\times3=18\)

6 x 1 = 6

6 x 2 = 12

6 x 3 = 18

6 x 1 = 6

6 x 2 = 12

6 x 3 = 18

ủng hộ mk nhé

C1: \(\dfrac{6}{7}\times\dfrac{1}{2}+\dfrac{6}{7}\times\dfrac{1}{4}=\dfrac{3}{7}+\dfrac{3}{14}=\dfrac{6}{14}+\dfrac{3}{14}=\dfrac{9}{14}\)

C2:\(\dfrac{6}{7}\times\dfrac{1}{2}+\dfrac{6}{7}\times\dfrac{1}{4}=\dfrac{6}{7}\times\left(\dfrac{1}{2}+\dfrac{1}{4}\right)=\dfrac{6}{7}\times\left(\dfrac{2}{4}+\dfrac{1}{4}\right)=\dfrac{6}{7}\times\dfrac{3}{4}=\dfrac{9}{14}\)

5/6 x 1/7 - 1/7 x 1/6

= 1/7 x (5/6 - 1/6)

= 1/7 x 2/3

= 2/21

8/15 : 4/5 x 3/2

= 2/3 x 3/2

= 1

a: =1/7(5/6-1/6)=1/7x2/3=2/21

b: =8/15x5/4x3/2=1

`5/6xx1/7-1/7xx1/6`

`= 1/7 xx (5/6-1/6)`

`= 1/7 xx 2/3`

`= 2/21`

`8/15: 4/5 xx3/2`

`= 2/3 xx 3/2`

`= 1`

Mình nghĩ 6 x 3 = 2

Đúng không nhỉ?

6x3=2
