James and Ahmik went to a bicycle show. Of the bicycles they saw at the show, 32% were blue, 25% were red, 25% were green, and 18% were black. In ratio form, what percent of the bicycles were red or black?

43:100

Step-by-step explanation:

Percentage of bicycles that are blue = 32%

Percentage of bicycles that are red = 25%

Percentage of bicycles that are green = 25%

Percentage of bicycles that are black = 18%

Percentage of bicycles that are red or black = 25% + 18% = 43%

Therefore, 43% will be written in ratio form as 43:100
