Answer:
5 batteries with a leftover time of 3 minutes
Step-by-step explanation:
If it takes the watch repairman 8 minutes to replace a battery on the watches
In 43 minutes, he will be able to replace [tex]\frac{43}{8}[/tex] batteries on the watches
[tex]\frac{43}{8}[/tex] =[tex]5\dfrac{3}{8}[/tex]
Therefore the watch repairman can replace 5 watch batteries.
He will have 3 minutes left over.
