Question

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

Answer 1

=2/5 + 2/3 + 3/4 + 3/5 + 1/3 + 1/4
=2 x (1/5 + 1/3) + 3 x (1/4 + 1/5) + (1/3 + 1/4)

=2 x 8/15 + 3 x 9/20 + 8/15

=8/15 x (1+2) + 3 x   9/20

=3 x 8/15 + 3 x 9/20

=3 x (8/15 + 9/20)

= 3 x 59/60

=59/20

Answer 2

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