Question

Answer 1

`10/3 - 8/3 =(10-8)/3 = 2/3`

`8/11 - 4/11 = (8-4)/11 = 4/11`

`4/18 - 1/9 = 2/9 - 1/9 =(2-1)/9 = 1/9`

`19/5 - 3/15 = 19/5 - 1/5 = (19-1)/5 = 18/5`

`3-16/11 = 33/11 - 16/11= (33-16)/11 = 17/11`

`9/8-1=9/8-8/8=(9-8)/8 = 1/8`

Answer 2

a,\(\dfrac{10}{3}-\dfrac{8}{3}=\dfrac{2}{3}\)

 

b,\(\dfrac{8}{11}-\dfrac{4}{11}=\dfrac{4}{11}\)

 

c,\(\dfrac{4}{18}-\dfrac{1}{9}=\dfrac{4}{18}-\dfrac{2}{18}=\dfrac{2}{18}=\dfrac{1}{9}\)

 

d,\(\dfrac{19}{5}-\dfrac{3}{15}=\dfrac{57}{15}-\dfrac{3}{15}=\dfrac{54}{15}=\dfrac{18}{5}\)

 

e,\(3-\dfrac{16}{11}=\dfrac{33}{11}-\dfrac{16}{11}=\dfrac{17}{11}\)

 

f,\(\dfrac{9}{8}-1=\dfrac{9}{8}-\dfrac{8}{8}=\dfrac{1}{8}\)

Answer 3

\(a,=\dfrac{10-8}{3}=\dfrac{2}{3}\\ b,=\dfrac{8-4}{11}=\dfrac{4}{11}\\ c,=\dfrac{2}{9}-\dfrac{1}{9}=\dfrac{2-1}{9}=\dfrac{1}{9}\\ d,=\dfrac{19}{5}-\dfrac{1}{5}=\dfrac{19-1}{5}=\dfrac{18}{5}\\ e,=\dfrac{33}{11}-\dfrac{16}{11}=\dfrac{33-16}{11}=\dfrac{17}{11}\\ f,=\dfrac{9}{8}-\dfrac{8}{8}=\dfrac{9-8}{8}=\dfrac{1}{8}\)
