Question

1/2+1/2

2/4+2/4

5/4+5/16

Answer 1

`1/2+1/2=(1+1)/2=2/2=1`

`2/4+2/4=(2+2)/4=4/4=1`

`5/4+5/16= 20/16+5/16=(20+5)/16=25/16`

Answer 2

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

\(\dfrac{2}{4}+\dfrac{2}{4}=\dfrac{4}{4}=1\)

\(\dfrac{5}{4}+\dfrac{5}{16}=\dfrac{20}{16}+\dfrac{5}{16}=\dfrac{25}{16}\)

 

Answer 3

\(\dfrac{1}{2}+\dfrac{1}{2}=\dfrac{1}{2}\times2=1\)
\(\dfrac{2}{4}+\dfrac{2}{4}=\dfrac{2}{4}\times2=1\)
\(\dfrac{5}{4}+\dfrac{5}{16}=\dfrac{20+5}{16}=\dfrac{25}{16}\)

Answer 4

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

 

\(\dfrac{2}{4}+\dfrac{2}{4}=\dfrac{2+2}{4}=\dfrac{4}{4}=1\)

 

\(\dfrac{5}{4}+\dfrac{5}{16}=\dfrac{20}{16}+\dfrac{5}{16}=\dfrac{20+5}{16}=\dfrac{25}{16}\)
