Question

2/5+6/9+3/4+3/5+1/3+1/4

Answer 1

`2/5+6/9+3/4+3/5+1/3+1/4`

`= ( 2/5 + 3/5 ) + ( 3/4 + 1/4 ) + ( 6/9 + 1/3 )`

`= 5/5 + 4/4 + 9/9`

`=1+1+1`

`=3`

Answer 2

\(\left(\dfrac{2}{5}+\dfrac{3}{5}\right)+\left(\dfrac{6}{9}+\dfrac{1}{3}\right)+\left(\dfrac{3}{4}+\dfrac{1}{4}\right)=\dfrac{5}{5}+\dfrac{3}{3}+\dfrac{4}{4}=1+1+1=3\)

Answer 3

=(2/5+3/5)+(6/9+1/3)+(3/4+1/4)

=1+1+1

=3

Answer 4

\(\left(\dfrac{2}{5}+\dfrac{3}{5}\right)+\left(\dfrac{6}{9}+\dfrac{1}{3}\right)+\left(\dfrac{3}{4}+\dfrac{1}{4}\right)\)

\(1+1+1=3\)

Answer 5

\(\dfrac{2}{5}+\dfrac{6}{9}+\dfrac{3}{4}+\dfrac{3}{5}+\dfrac{1}{3}+\dfrac{1}{4}\)

\(=\dfrac{2}{5}+\dfrac{3}{5}+\dfrac{2}{3}+\dfrac{1}{3}+\dfrac{3}{4}+\dfrac{1}{4}\)

\(=1+1+1\)

\(=3\)
