Hey there! I'm happy to help!
If we want to turn this into a decimal, we only need to find what the fraction is as a decimal because we already know the whole number
QUESTION 1
We know that our decimal is 4 point something. We know that this something is 1/5. To turn a fraction into a decimal, you just divide the numerator by the denominator.
1÷5=0.2
We add the whole number and fraction.
4+0.2=4.2.
QUESTION 2
14÷15=0.933333 repeating
We add this to the whole number.
12.93333333 repeating.
QUESTION 3
5÷32=0.15625
We add this to the whole number.
5.15625
Have a wonderful day! :D
Answer:
The situation is Multiplicative.
The equation will be 
Step-by-step explanation:
We are given the table:
Input (x) 5 8 11
Output (y) 10 16 22
Looking at the table, we see that the value of x is doubled to get value of y
Looking at the trend: 5(2) = 10
8(2) = 16
11(2) = 22
The value of x is multiplies by 2 to get value of y.
So, The situation is Multiplicative.
Now, The equation will be 
because we saw the trend, that every value of x is multiplied by 2 to get value of y.
