$18 = y$

Explanation:

$\frac{6}{23} = \frac{y}{69} | \cdot 69$
$\frac{6 \cdot 69}{23} = \frac{y}{\cancel{69}} \cancel{\cdot 69}$
$\frac{6 \cdot 3 \cdot \cancel{23}}{\cancel{23}} = y$
$6 \cdot 3 = 18 = y$

See method below.

Explanation:

You want to rearrange the equation so that you isolate y on one side.

$\frac{6}{23} = \frac{y}{69}$

You can multiply both sides by 69 to get the following:

$\frac{6}{23} \times 69 = y$

$\frac{6}{23} \times 69 = 18$

therefore $y = 18$
