Answer 1

The gestation period of rhinos ​(487 ​days) is​ 121. 3 percent longer than the gestation period of bears ​(220 ​days).

Explanation:

Given:

Gestation period of rhinos = 487 ​days

Gestation period of bears = 220 ​days

To Find:

Percentage increase = ?

Solution:

The percentage increase =
`\frac{ \text{new value} - \text{final value} }{\text{final value}} * 100`

On substituting the values,

=
`( 487 - 220)/(220)* 100`

=
`(267)/(220)* 100`

=>
`1.213 * 100`

=> 121.3 %
