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
