Question

4/15+8/13+11/5+5/13

Answer 1

4/15 + 8/13 + 11/5 + 5/13

= (4/15 + 11/5) + (8/13 + 5/13)

= (4/15 + 33/15) + 13/13

= 37/15 + 1

= 52/15.

Answer 2

     \(\frac{4}{15}+\frac{8}{13}+\frac{11}{15}+\frac{5}{13}\)

\(=\left(\frac{4}{15}+\frac{11}{15}\right)+\left(\frac{8}{13}+\frac{5}{13}\right)\)

\(=\frac{15}{15}+\frac{13}{13}\)

\(=1+1\)

\(=2\)

Answer 3

4/15+8/13+11/5+5/13

=(4/15+11/5)+(8/13+5/13)

=37/15+1

=37/15+15/15

=52/15
