Given parameters:

Number of pencils = [tex]4\frac{1}{2}[/tex] pencils

Time taken = [tex]3\frac{1}{3}[/tex] minutes

Unknown:

Number of pencils produced in 1 minute;

Solution:

To solve this problem, let us first find the rate of the machine;

       Rate of machine = [tex]\frac{number of pencils }{time taken}[/tex]

       Rate of machine = [tex]\frac{\frac{9}{2} }{\frac{10}{3} }[/tex]   = [tex]\frac{9}{2} x \frac{3}{10}[/tex]   = [tex]\frac{27}{20}[/tex] pencils/minute

Now, number of pencils produces in 1 minute;

            Number of pencils  = rate of machine x time taken

             Number of pencils = [tex]\frac{27}{20}[/tex]  pencils/ min x 1 min

             Number of pencils = [tex]\frac{27}{20}[/tex]pencils

The number of pencils produced in 1 minute is [tex]\frac{27}{20}[/tex]
