Hint: To convert a value in meters into centimeters, we have to multiply that value by 100. Likewise, to convert a value in centimeters into meters, we have to divide that value by 100. Therefore, we have to divide 250 by 100.

Complete step by step answer:
We have to express 250 cm in meters. We know that to convert a value in meters into centimeters, we have to multiply that value by 100. We can write the conversion as follows.
1 meter = 100 cm
Now, to convert a value in centimeters into meters, we have to divide that value by 100. We can write this mathematically as
$1\text{ cm}=\dfrac{1}{100}\text{m}$
We are given 250 cm. We have to convert this into meters. For this, we will divide 250 by 100.
$\Rightarrow 250\text{ cm}=\dfrac{250}{100}\text{ m}$
Let us cancel the zeroes from the numerator and denominator.
$\Rightarrow 250\text{ cm}=\dfrac{25\require{cancel}\cancel{0}}{10\require{cancel}\cancel{0}}\text{ m}$
We can write the result of above simplification as
$\Rightarrow 250\text{ cm}=\dfrac{25}{10}\text{ m}$
We have to divide 25 by 10. We can obtain the result by moving the decimal point one unit to the left. We can write 25 as 25.0. Therefore, when moving the decimal point one place to the left, we will get 2.5. We can write the result of $\dfrac{25}{10}$ as
$\Rightarrow 250\text{ cm}=2.5\text{ m}$
Hence, 250 cm is 2.5 m.

Note: Students must be thorough with the conversions. They have a chance of making a mistake when converting centimeters into meters by multiplying the given value in centimeters by 100. Students must never forget to write the units at the end.
