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

A. 2.77777...

`B. -(7)/(3)`

Explanation:

A rational number can be written in the form
`(a)/(b)`,where
`b\\e 0` and
`a,b` are integers.

The number
`2.77777...` can be rewritten as
`(25)/(9)`.

This is a rational number.

`-(7)/(3)` is also a rational number.

`√(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.
