Kerion will take 1.5 hours to make 9 necklaces.
Step-by-step explanation:
Given,
12 necklaces are made in 2 hours.
We will find unit rate in terms of necklaces.
12 necklaces = 2 hours
1 necklace = [tex]\frac{2}{12}\ hours[/tex]
1 necklace = [tex]\frac{1}{6}*9[/tex]
For 9 necklaces, we will multiply 9 with unit rate
9 necklaces = [tex]\frac{1}{6}*9[/tex]
9 necklaces = 1.5 hours
Kerion will take 1.5 hours to make 9 necklaces.
