$x = 6$ $x=6$

To get from $1.5$ $1.5$ to $3$ $3$ , you multiply by $2$ $2$ .

( $1.5 \times 2 = 3$ $1.5xx2=3$ ).

So hence, for the ratio to be equivalent, you need to find a number, such that when you multiply it by $2$ $2$ , you get $12$ $12$ .

This number is hence $\frac{12}{2} = 6$ $12/2=6$ .

( $6 \times 2 = 12$ $6xx2=12$ )
