The number is $15$.

#### Explanation:

Consider the number as $x$.

$x \times \frac{120}{100} = 18$

Multiply both sides by $\frac{100}{120}$.

$x = 18 \times \frac{100}{120}$

$x = 18 \times \frac{10 \cancel{0}}{12 \cancel{0}}$

$x = 18 \times \frac{5 \cancel{10}}{6 \cancel{12}}$

$x = 3 \cancel{18} \times \frac{10}{1 \cancel{6}}$

$x = 3 \times 5$

$x = 15$
