Question

Các bạn giúp mk với!!!

Answer 1

Đi mừ, giúp cái coi 

Answer 2

ko giúp đâu

Answer 3

\(=\dfrac{1}{6}-\dfrac{1}{8}=\dfrac{1}{24}\\ =10-\dfrac{1}{8}=\dfrac{79}{8}\)

Answer 4

Nhớ tick

= 1/24

=79/8

Answer 5

\(\dfrac{1}{6}-\dfrac{1}{8}=\dfrac{8-6}{48}=\dfrac{2}{48}=\dfrac{1}{24}\)

\(\dfrac{5}{2}\times\dfrac{4}{1}-\dfrac{1}{8}=\dfrac{20}{2}-\dfrac{1}{8}=10-\dfrac{1}{8}=\dfrac{79}{8}\)

Answer 6

\(\dfrac{1}{2}\times\dfrac{1}{3}-\dfrac{1}{8}=\dfrac{1}{6}-\dfrac{1}{8}=\dfrac{1.4-1.3}{24}=\dfrac{1}{24}\)

\(\dfrac{5}{2}:\dfrac{1}{4}-\dfrac{1}{8}=\dfrac{5}{2}\times\dfrac{4}{1}-\dfrac{1}{8}=10-\dfrac{1}{8}=\dfrac{8.10-1}{8}=\dfrac{79}{8}\)

Answer 7

1/2 x 1/3 - 1/8  = 1/6 - 1/8= 8/48 - 6 /48 = 2/48 = 1/ 12

5/2 :1/4 -1/8 = 5/2 x 4/1 - 1/8 = 10/1 - 1/8 = 80/8 - 1/8 = 79/8

Answer 8

1/2 x 1/3 - 1/8 = 1/6 - 1/8 =2/48

5/2 : 1/4 - 1/8 = 10 - 1/8 = 79/8
