Answer:
Yes, her reasoning is correct
Step-by-step explanation:
Given the ratio: 109.2 : 6
Written in fractional form, we have:
![109.2: 6=\dfrac{109.2}{6}](https://tex.z-dn.net/?f=109.2%3A%206%3D%5Cdfrac%7B109.2%7D%7B6%7D)
Now:
Therefore, the student's reasoning is correct. In fact, as a check:
![\dfrac{109.2}{6}=18.2\\\\\dfrac{1092}{60}=18.2](https://tex.z-dn.net/?f=%5Cdfrac%7B109.2%7D%7B6%7D%3D18.2%5C%5C%5C%5C%5Cdfrac%7B1092%7D%7B60%7D%3D18.2)
We would obtain the same result in both cases.
