Answer:

The answer is the option B. [tex]1\ to\ 2, 1 :2, 1/2[/tex]

Step-by-step explanation:

Let

a------> the months that have [tex]30[/tex] days

b----> the months with other than [tex]30[/tex] days

we know that

[tex]a+b=12[/tex]

[tex]a=4\ months[/tex]

Find the value of b

[tex]4+b=12[/tex] ------> [tex]b=8\ months[/tex]

therefore

the ratio is equal to

[tex]\frac{a}{b}=\frac{4}{8}=\frac{1}{2}[/tex]
