C.2 to 1, 2:1, 2/1


D.3 to 1, 3:1, 3/1

Answer 1

a 4 to 30
b 4:30
c 4/30
or for your choices c

Answer 2

The answer is the option B.
`1\ to\ 2, 1 :2, 1/2`

Explanation:

Let

a------> the months that have
`30` days

b----> the months with other than
`30` days

we know that

`a+b=12`

`a=4\ months`

Find the value of b

`4+b=12` ------>
`b=8\ months`

therefore

the ratio is equal to

`(a)/(b)=(4)/(8)=(1)/(2)`
