Answer:
1.5 hours
Step-by-step explanation:
Given : Kerion can make 12 necklaces in 2 hours.
To Find : How long will it take her to make 9 necklaces?
Solution :
Time taken to make 12 necklaces = 2
Time taken to make 1 necklace = \(\frac{2}{12}\)
So, Time taken to make 9 necklace = \(\frac{2}{12} \times 9\)
= \(1.5\)
Hence it will take her 1.5 hours to make 9 necklaces
