Identify the two rational numbers.

A. 2.777777...
B. fraction -7/3
C. square 3
D. 2.7182818459...

Answer 1

Hello,

Rational numbers are numbers that can be represented by fractions that consist of integers.

In this case, B. -7/3 is already a fraction that consists of integers, so it is a rational number.
C. square 3 is = $3^{2}$ = 9, which can be represented by 9/1, so it is also a rational number.

A and D are incorrect as they cannot be represented by fractions that consist of integers.

The answers are B and C.

Hope this helps!

Answer 2

Answer:

A. 2.77777...

$B. -\frac{7}{3}$

Step-by-step explanation:

A rational number can be written in the form $\frac{a}{b}$,where $b\ne 0$ and $a,b$ are integers.

The number $2.77777...$ can be rewritten as $\frac{25}{9}$.

This is a rational number.

$-\frac{7}{3}$ is also a rational number.

$\sqrt{3}=1.73205080...$

No recurring pattern so it is an irrational number

$2.7182818459....$ also has no recurring pattern. This is also an irrational number.
