Question

4 1/2 +1/2 : 5 1/2

Answer 1

\(=\dfrac{9}{2}+\dfrac{1}{2}:\dfrac{11}{2}=\dfrac{9}{2}+\dfrac{1}{11}=\dfrac{99+2}{22}=\dfrac{101}{22}\)

Answer 2

`4 1/2+1/2:5 1/2=9/2+1/2:11/2=9/2+1/2xx2/11=9/2+1/11=99/22+2/22=101/22`

Answer 3

\(4\dfrac{1}{2}+\dfrac{1}{2}:5\dfrac{1}{2}\)

\(=\dfrac{9}{2}+\dfrac{1}{2}:\dfrac{11}{2}\)

\(=\dfrac{9}{2}+\dfrac{1}{2}\times\dfrac{2}{11}\)

\(=\dfrac{9}{2}+\dfrac{1}{11}\)

\(=\dfrac{99}{22}+\dfrac{2}{22}\)

\(=\dfrac{101}{22}\)

Answer 4

`4 1/2 + 1/2 : 5 1/2`

`=9/2 +1/2 : 11/2`

`=9/2 + 1/2 . 2/11`

`=9/2 + 1/11`

`=99/22 +2/22`

`=101/22`
