Answer
4.5
Work Step by Step
$\frac{y}{9}$ =$\frac{0.6}{1.2}$
1.2$\times$ y = 9$\times$0.6 set cross products equal
1.2y = 5.4 multiply
$\frac{1.2y}{1.2}$=$\frac{5.4}{1.2}$
y=$\frac{1.8}{0.4}$
y=$\frac{18}{4}$
y=4.5
Check
$\frac{y}{9}$ =$\frac{0.6}{1.2}$
$\frac{4.5}{9}$ =$\frac{0.6}{1.2}$
0.5=0.5 True
4.5 is the solution
