Question

Lakshmi is 150 cm tall. What is her height in meters?
A.1 meter
B.1.5 meters
C.15.0 meters
D.0.15 meters

Answer 1

Hint: In this question, we need to determine the equivalent value of 150 centimeters into meters. For this, we will use the conversion method to transverse centimeters to meters.

Complete step-by-step answer:
As the number of cells in between the centimeters and the meters are two so, 100 will be divided.
To convert centimeters to meters, we need to divide the absolute value by 100. Mathematically, $ m = \dfrac{{cm}}{{100}} $. In other words, 100 centimeters is equivalent to 1 meter.
Here, in the question Lakshmi is 150 cm tall and we need to evaluate her height in meters. So, divide the absolute value of Lakshmi’s height by 100 to determine her height in meter equivalent.
$
  height = 150cm \\
   = \dfrac{{150}}{{100}}meters \\
   = 1.5meters \\
 $
Hence, the height of Lakshmi is 1.5 meters which is also equivalent to 1.5 meters.
So, the correct answer is “Option B”.

Note: Alternatively, we can also solve this problem by using the unitary method.
We know that 100 cm is equivalent to 1 meter.
So, $ 1cm = \dfrac{1}{{100}}meter $
Hence, by using unitary method, we can say that 150 centimeter is equivalent to
 $
  150cm = \left( {\dfrac{1}{{100}} \times 150} \right)meters \\
   = 1.5meters \\
