Answer: rounded: 2400
60 * 40
Actual: 2508
Step-by-step explanation:
Answer:
The value of the unit rate is 8
Step-by-step explanation:
we know that
To calculate the unit rate simply divide the first number by the second number
so
![12:1\frac{1}{2}](https://tex.z-dn.net/?f=12%3A1%5Cfrac%7B1%7D%7B2%7D)
Convert mixed number to an improper fraction
![1\frac{1}{2}=1+\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%3D1%2B%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B1%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B3%7D%7B2%7D)
substitute in the expression above
![12:\frac{3}{2}=\frac{24}{3}=8](https://tex.z-dn.net/?f=12%3A%5Cfrac%7B3%7D%7B2%7D%3D%5Cfrac%7B24%7D%7B3%7D%3D8)
