Answer:
No.
Step-by-step explanation:
We can set this proportion up as:
[tex]\frac{4.2}{1.5}=\frac{12}{5}[/tex]
For this to be true, cross-products need to be equal:
[tex]4.2(5)=12(1.5)[/tex],
However, we can see that this is not the case:
[tex]4.2\cdot 5 \neq 12 \cdot 1.5[/tex]
Therefore, these ratios are not proportional.
