Question

Write any three rational number between -2 and 0

Answer 1

Answer:

-1.5, -1.88, -0.987654 are some rational numbers between -2 and 0.

Step-by-step explanation:

There are infinite rational numbers between -2 and 0.

These include:

-0.1, -0.2, -0.3, ...., -1.99999

Choosing any three at random,

we have -1.5, -1.88, -0.987654

Answer 2

Given: Two numbers -2 and 0

To find: Three rational numbers between the given numbers

Solution:

Given numbers are -2 and 0.

To insert rational numbers between -2 and 0, we need to find the average of -2 and 0.

i.e., $\frac{-2 \ + \ 0}{2} = \frac{-2}{2} = -1$

We get, -2 < -1 < 0

Now we need to find another rational number between -2 and -1.

i.e., $\frac{[-2 \ + \ (-1)]}{2}= \frac{-3}{2}$

We get, -2 < $\frac{-3}{2}$ < -1 < 0

Now we need to find another rational number between -1 and 0.

i.e., $\frac{-1 \ + \ 0}{2} = \frac{-1}{2}$

We get, -2 < $\frac{-3}{2}$ < -1 < $\frac{-1}{2}$ < 0

Hence, three rational numbers between -2 and 0 are:

$\frac{-3}{2}$ ,  -1 and  $\frac{-1}{2}$
