Question

2. Bianca is one third as old as her
sister who is 27 years old. How old is
Bianca?

Answer 1

9 because 27 divided by 3 equals 9

Answer 2

Bianca is 9 years old.

Explanation:

Definition:

Age: The amount of time that has passed since something was born or created.

Answer:

In order to find Bianca's age, we can use the following equation:

`\sf \textsf{Bianca's age }= (1)/(3)* \textsf{ Sister's age}`

We know that Bianca's sister is 27 years old, so we can plug or substitute this value into the equation to get:

`\sf \textsf{Bianca's age }= (1)/(3)* \textsf{ 27 years}`

Bianca's age = 9 years

Therefore, Bianca is 9 years old.
