Answer 2

\(a,\dfrac{1}{2}\times\dfrac{1}{3}-\dfrac{1}{8}=\dfrac{1}{6}-\dfrac{1}{8}=\dfrac{4}{24}-\dfrac{3}{24}=\dfrac{1}{24}\\ b,\dfrac{5}{2}:\dfrac{1}{4}-\dfrac{1}{8}=\dfrac{5}{2}\times4-\dfrac{1}{8}=10-\dfrac{1}{8}=\dfrac{80}{8}-\dfrac{1}{8}=\dfrac{79}{8}\)

Answer 3

a) 1/6- 1/8

= 1/24

b) 5/2 x 4/1-1/8

= 20/2 - 1/8

= 10-1/8

= 79/8

Answer 4

\(a,\dfrac{1}{2}\times\dfrac{1}{3}-\dfrac{1}{8}=\dfrac{1}{6}-\dfrac{1}{8}=\dfrac{4}{24}-\dfrac{3}{24}=\dfrac{1}{24}\)

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

Answer 5

\(a,=\dfrac{1}{6}-\dfrac{1}{8}=\dfrac{8}{48}-\dfrac{6}{48}=\dfrac{2}{48}=\dfrac{1}{14}\\ b,=10-\dfrac{1}{8}=\dfrac{80}{8}-\dfrac{1}{8}=\dfrac{79}{8}\)

Answer 6

a)1/2x1/3-1/8=1/6-1/8=1/24

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

Answer 7

a) 1/2 x 1/3 - 1/8

= 1/6 - 1/8

= 4/24 - 3/24

= 1/24
