Final answer:
To find the ratio of black rabbits to all rabbits, the number of black rabbits (175) is divided by the total number of rabbits (325) and simplified to get a ratio of 7:13.
Step-by-step explanation:
The question is asking to find the ratio of black rabbits to the total number of rabbits. To calculate this, you can put the number of black rabbits in relation to the total number of rabbits which is 325.
So, the ratio is:
175 black rabbits / 325 total rabbits
To simplify the ratio, we divide both the numerator and the denominator by the greatest common divisor, which in this case is 25.
175 ÷ 25 = 7
325 ÷ 25 = 13
Thus, the simplified ratio is 7:13.
