Answer:

A = 1

Explanation:

$frac. \: (4)/(12) = (a)/(3)$

$( \: \: \: 4 \: / \: x \: = \: a)/(12 \: / \: x \: = \: 3)$

$( \: \: 4 \: / \: x \: = \: a)/(12 \: / \: 4 \: = \: 3)$

$( \: \: 4 \: / \: 4 \: = \: a)/(12 \: / \: 4 \: = \: 3)$

$( \: \: 4 \: / \: 4 \: = \: 1)/(12 \: / \: 4 \: = \: 3)$

a= 1
