Question

A rational number between 1/2 and 1/5 is _____.​

Answer 1

So, a rational number between

4

1

and

3

1

=

2

4

1

+

3

1

=

24

7

Now, another rational number between

4

1

and

24

7

=

2

4

1

+

24

7

=

48

13

Now, another rational number between

3

1

and

24

7

=

2

3

1

+

24

7

=

48

15

Hence, required two rational numbers between

4

1

and

3

1

are

24

7

,

48

13

,

48

15

Answer 2

Answer:

A rational numbers between $\frac{1}{2}$ and $\frac{1}{5}$  is  $\frac{3}{10}$ .

Step-by-step explanation:

To find : a rational numbers between and .

Solution:

• According question we have to find a rational number between $\frac{1}{2}$ and $\frac{1}{5}$ for this we need to equalize denominators of the rational numbers by taking LCM.
• Therefore, LCM = $10$
• Now, multiplying numerators by same numbers as multiplied by denominator to make LCM .
• We get , $\frac{1}{2}=\frac{1 \times 5}{10}=\frac{5}{10} and \frac{1}{5}=\frac{1 \times 2}{10}=\frac{2}{10}$
• Now, we can find two rational numbers between $\frac{5}{10}$ and $\frac{2}{10}$ .
• One of the rational number is $\frac{3}{10}$ .
