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]
