Question

The gestation period of rhinos (487 days) is what percent longer than the gestation period of pigs (115)?

A) 322.61%
B) 222.61%
C) 111.30%
D) 76.52%

Answer 1

The gestation period of rhinos is 223.48% longer than the gestation period of pigs. After subtracting the original 100%, the nearest answer choice is B) 222.61%.

Step-by-step explanation:

The question asks us to calculate how much longer the gestation period of rhinos is compared to that of pigs. To find this, we first need to calculate the difference in days between the two gestation periods and then determine what percent the difference is of the gestation period of pigs.

The gestation period for rhinos is 487 days, and for pigs, it's 115 days. The difference in the gestation periods is:

487 days - 115 days = 372 days.

Now, we want to find out what percent 372 days is of 115 days:

(372 days / 115 days) × 100% = 323.48%

However, since we're looking for how much longer the gestation period is, we subtract 100% to get the increase in percent:

323.48% - 100% = 223.48%

The closest answer choice that matches this calculation is:

B) 222.61%
