Question

solve the proportion (with work please) $\frac{10}{5} =\frac{n}{10}$

Answer 1

Solution:

If $\frac{a}{b} = \frac{c}{d}$ then $ad=cb$. You could use that to solve the proportion,

$\frac{10}{5}=\frac{n}{10} \\5n=10(10)\\5n=100\\\frac{5}{5}n=\frac{100}{5} \\n=20$

Answer:

$n=20$

Check:

$\frac{10}{5} =\frac{20}{10} \\2=2$
