Answer:
Incorrect
Step-by-step explanation:
We are given that a number 3.52
Dori claims that 3.52 is not a rational number because it is not written as a ratio of integers.
We have to find she is correct.
Rational number : It is that number which can be written in the from of
where p and q are integers,
.
When we remove decimal then we write 100 in denominator because two digits after decimal point.
![3.52=\frac{352}{100}=\frac{325}{2^2\times 5^2}](https://tex.z-dn.net/?f=3.52%3D%5Cfrac%7B352%7D%7B100%7D%3D%5Cfrac%7B325%7D%7B2%5E2%5Ctimes%205%5E2%7D)
If the denominator of given number can be written as ![2^n\cdot 5^m](https://tex.z-dn.net/?f=2%5En%5Ccdot%205%5Em)
Then the number is terminating rational number.
Hence, the given number is rational number.
Therefore, Dori is wrong.
