${\boxed{\mathcal{\red{Step-by-step\:explanation.}}}}$

✰ Let $x$ be the number of boys in the class.

✰ As per the question,

$Total \: number \: of \: students \: in \: the \: class \: = \: 48 \\ \: ➪ \: No. \: of \: girls \: + \: no. \: of \: boys \: = \: 48 \\ \: ➪ \: 16\: + x \: = \: 48 \\ \: ➪ \: x \: =\: 48\: - 16 \\ \: ➪\: x\: = \: 32$

Therefore, the total number of boys in the class is 32.

☑ Hence, the ratio of boys to girls is

$=\frac{32}{16}\\=\frac{2}{1}$

$= 2:1$
