If the ratio of purple bikes to red bikes is 8 to 12 and there are a total of 100 bikes, how many of them are purple? *

Add the ratio: 8 + 12 =20

Divide total bike by that: 100/20 = 5

Multiply each part of the ratio by that:

8 x5 = 40

12 x 5 = 60

40 bikes are purple

60 bikes are red

40

Step-by-step explanation:

Purple:Red = 8:12
