Bot GPT 4-o mini To convert each of the rates to unit rates, we need to express them in the form of "x per 1 unit."
Let's break down each option:
A. 2
- This is already a simple quantity with no ratio. We can interpret this as 2 per 1, or simply 2.
B. 12 1/2
- This can be converted to an improper fraction: \[ 12 \frac{1}{2} = \frac{25}{2} \]
- As a unit rate, it would be \(\frac{25}{2}\) per 1, which is: \[ 12.5 \]
C. 981 98/1
- This notation is not standard. Assuming this means \(981\) with a unit of \(98\):
- Thus, it’s \( \frac{981}{98} \) which can be calculated as: \[ 981 \div 98 = 10.0 \]
D. 198 1/98
- Interpreting this as \(198\) with a unit of \(98\):
- Thus, it’s \( \frac{198}{98} \). Simplifying gives: \[ 198 \div 98 \approx 2.02 \]
In summary, the unit rates are:
- A: 2 per 1
- B: 12.5 per 1
- C: 10 per 1
- D: 2.02 per 1
