Given: A tire can be made in 1 1/2 minutes
To Determine: The number of tires that would be made in 6 minutes
Solution
Let the number of tires made in 6 minutes be x. So
[tex]\begin{gathered} 1tire=1\frac{1}{2}mniutes \\ xtires=6minutes \\ 1tire=\frac{3}{2} \\ xtires=6 \\ Cross\text{ }multiply \end{gathered}[/tex][tex]\begin{gathered} \frac{3}{2}x=6 \\ 3x=12 \\ x=\frac{12}{3} \\ x=4 \end{gathered}[/tex]Hence, the number of tires made in 6 minutes is 4
