there is a total of 25 bicycles. if the ratio of gray bicycles to black bicycles is 6 to 9 how many of them are black?

Answers

25 bicycles
gray : black
6 : 9 (6+9=15)

25 divided by 15 = 1.666666667
x 9 (that's how many blacks)
= 15
there are 15 blacks

Final answer:

To find the number of black bicycles in a total of 25 bicycles given a ratio, divide the total number of bicycles by the total number of parts in the ratio and multiply by the number of parts representing black bicycles.

Explanation:

To find the number of black bicycles, we first need to find the total number of parts in the ratio. The ratio of gray bicycles to black bicycles is 6 to 9, which means the total number of parts is 6 + 9 = 15. We can then calculate the number of black bicycles by dividing the total number of bicycles by the total number of parts and multiplying by 9. So, the number of black bicycles is (25/15) x 9 = 15 bicycles.
