Answer:

28 bikes are blue

Step-by-step explanation:

Set up the ratio:

Blue : Black

4 : 5

Find the total # of bikes in the ratio:

4 + 5 = 9

Find the relationship between 63 and 9:

63/9 = 7

Multiply both sides of the ratio by 7:

4(7) = 28

5(7) = 35

28 : 35

Therefore, the number of blue bikes is 28.
