Ages

The father is 36 years old, and his daughter is four years old. Write down the ratio of the age of the father and daughter. In what ratio will the ages of father and daughter be after four years?

Correct answer:

x =  9:1
y =  5:1

Step-by-step explanation:

$$\begin{gathered} f=36 \\ d=4 \\ x=\frac{f}{d}=\frac{36}{4}=9=9:1 \end{gathered}$$

$y=\frac{f+4}{d+4}=\frac{36+4}{4+4}=5=5:1$
