we have the expression
[tex]\frac{3}{5}\colon\frac{6}{8}[/tex]Multiply in cross
[tex]\frac{3}{5}\colon\frac{6}{8}=\frac{3\cdot8}{6\cdot5}=\frac{8}{2\cdot5}=\frac{4}{5}[/tex]therefore
Remember that
(3/5) : (6/8)=(3/5)x(8/6)
so
Option B has the same value
Verify option D and option E
Option D
(24/40):(30/40)=(24*40)/(40*30)=24/30=4/5 -----> has the same value
Option E
(24/40)x(40/30)=(24*40)/(40*30)=24/30=4/5 -----> has the same value
therefore
the answer is
