Solution:
If [tex]\frac{a}{b} = \frac{c}{d}[/tex] then [tex]ad=cb[/tex]. You could use that to solve the proportion,
[tex]\frac{10}{5}=\frac{n}{10} \\5n=10(10)\\5n=100\\\frac{5}{5}n=\frac{100}{5} \\n=20\\[/tex]
Answer:
[tex]n=20[/tex]
Check:
[tex]\frac{10}{5} =\frac{20}{10} \\2=2[/tex]
Hope this was helpful.
