Question

Valerie is $64\text{ }inches$ tall. About how many centimeters tall is Valerie (1 inch is 2.5 centimeters)?

Answer 1

Hint: In this question, we have to find the height of the Valerie in centimeters. The given height of Valerie is in inches; therefore, we have to convert it into centimeters. For that, we will use the basic mathematical rules to get the required result. We will use the formula $1\text{ }inch=2.5\text{ }centimetres$ . Then, we will multiply both sides of the equation by 64 and make further calculations, to get the required solution to the problem, which is the height of Valerie in centimeters.

Complete step by step answer:
According to the question, we have to find the height of Valerie in centimeters.
So, we will apply the inch-centimeter formula to get the solution for the same.
The inches given to us is $64\text{ }inches$
First, we will use the inch-centimeter formula, which is
$1\text{ }inch=2.5\text{ }centimetres$
Now, we will multiply $64$ on both sides in the above equation, we get
$\Rightarrow 1\times 64\text{ }inch=2.5\times 64\text{ }centimetres$
On further solving the above equation, we get
$\Rightarrow 64\text{ }inch=160\text{ }centimetres$ which is our required solution to the problem

Therefore, Valerie is $64\text{ }inch$ in height, and when we convert it into centimeters, we get the height of Valerie in $160\text{ centimetres}$.

Note: While solving this problem, do mention the units in each step to avoid confusion. Also, you can use the short form of the units, that is, for the centimeters use cm and for the inches you can use inches. Always mention the formula at the beginning of your solution so that you will not get confused and get an accurate solution to the problem.
