Answer 2

Answer:

1. True,  the sum of two rational expressions is always a rational expression.

2. It is also true that the product of two rational expressions is always a rational expression.​

Explanation:

• Rational number - A rational number can be stated mathematically as the ratio or fraction $\frac{p}{q}$ of two numbers, where p and q are the numerator and denominator, respectively.

• Since integers are closed under addition and multiplication, adding two rationals is equivalent to adding two of these fractions, which will produce a new fraction with the same form.

• Two rational numbers are added to create a third rational number.

• We'll use two rational numbers to demonstrate that the sum of those two numbers is also rational.

• Two rational numbers can be combined to form the rational number $\frac{1}{14}$ by multiplying $\frac{1}{4}$ ×  $\frac{2}{7}$ = $\frac{1}{14}$.
