Question

Annas3 dad is 36. He is 9 times as old as she is. How old is Anna

Answer 1

Concept

Let Annas age = y

Therefore, his dad age = 9y

From the question,

Equate 9y = 36

Next

Divide 9 on both side to get:

`\begin{gathered} (9y)/(9)\text{ = }(36)/(9) \\ y\text{ = 4} \end{gathered}`

Therefore, Anna age is 4

Final answer

Anna is 4 years old
