Answer :
5/n=(3/2)/(5/5+4/5)
5/n=(3/2)/(9/5)
5/n=(3/2)*(5/9)
5/n=15/18=5/6
5/n=5/6
30/n=5
5n=30
Therefore: n=6.
5/n=(3/2)/(9/5)
5/n=(3/2)*(5/9)
5/n=15/18=5/6
5/n=5/6
30/n=5
5n=30
Therefore: n=6.
[tex] \frac{5}{n} = \frac{1.5}{1.8} \ \ \ \Leftrightarrow\ \ \ 5\cdot1.8=1.5\cdot n \ \ \ \Leftrightarrow\ \ \ 9=1.5n\ /:1.5\\\\n=6[/tex]
