21 is a rational number because it is an integer, which can be converted into a fraction.

Step-by-step explanation:

When a denominater and numerator are integers and gives a quotient then it is a rational number.

21/1, where 21 is denominator and 1 is numerator the quotient is 21. Therefore 21 is a rational number which can also be considered as a ratio.

Answer:

option D

Step-by-step explanation:

$x^{2} + y^{2} = 16\\\\x^{2} = 16- y^{2}$

equation 2:

$\frac{x^{2}}{4} - \frac{y^{2}}{25} = 1$

so we have:

$\frac{16- y^{2} }{4}-\frac{y^{2}}{25}= 1$
