Question

9/5:17/15+8/5:17/15

Answer 1

\(\frac{9}{5}:\frac{17}{15}+\frac{8}{5}:\frac{17}{15}=\frac{9}{5}.\frac{15}{17}+\frac{8}{5}.\frac{15}{17}=\frac{15}{17}\left(\frac{9}{5}+\frac{8}{5}\right)=\frac{15}{17}.\frac{17}{5}=3\)

Answer 2

\(\frac{9}{5}:\frac{17}{15}+\frac{8}{5}:\frac{17}{15}\)= \(\left(\frac{9}{5}+\frac{8}{5}\right):\frac{17}{15}\)

=\(\frac{17}{5}.\frac{15}{17}\)= 3

Answer 3

9/5 : 17/15 + 8/5 : 17/15

= 17/15 : ( 9/5 + 8/5 )

= 17/15 : 17/5

= 1/3
