Ratios are used to relate two or more quantities

The number of motor bikes that pass the intersection is 14

The given parameters are:

[tex]Cars: Bikes =7 : 2[/tex]

[tex]Total = 63[/tex]

The number of motor bikes is calculated using:

[tex]Bikes = \frac{Bikes\ ratio}{Car\ ratio + Bike\ ratio} \times Total[/tex]

This gives

[tex]Bikes = \frac{2}{7 + 2} \times 63[/tex]

[tex]Bikes = \frac{2}{9} \times 63[/tex]

Divide 63 by 9

[tex]Bikes = 2 \times 7[/tex]

[tex]Bikes = 14[/tex]

Hence, the number of motor bikes that pass the intersection is 14
