The most basic definition of proportions is that they're just equivalent fractions. For proportions, the following holds true:

$\sf{(a)/(b)=(c)/(d)}$

To solve proportions, we cross - multiply,

Let's try applying this skill with this problem:

$\sf{(7)/(n)=(8)/(7)}$

Multiply 7 times 7, and n times 8:

$\sf{49=8n}$

Divide each side by 8:

$\sf{n=6.125}$

Hence, n = 6.125, or 6.13 if it's rounded to the nearest tenth.

$\rule{350}{4}$
