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

[tex]12:1\frac{1}{2}[/tex]

Convert mixed number to an improper fraction

[tex]1\frac{1}{2}=1+\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}[/tex]

substitute in the expression above

[tex]12:\frac{3}{2}=\frac{24}{3}=8[/tex]
