Answer 2

Answer:

The 3 rational numbers are $\frac{7}{10},\frac{11}{40}$ and $\frac{17}{40}$

Step-by-step explanation:

• The first rational number is the mean of the two numbers given
  $(\frac{1}{5} +\frac{1}{2})\frac{1}{2} = \frac{7}{20}$
• Hence our 1st rational number is $\frac{7}{20}$
• Now for the 2nd rational number we need to take out the mean of 1st fraction and the first rational number
  $(\frac{7}{20} +\frac{1}{5})\frac{1}{2} = \frac{11}{40}$
• Hence our 1st rational number is $\frac{11}{40}$
• Now for 3rd rational number we have to find mean of 2nd fraction and 1st rational number
  $(\frac{7}{20} + \frac{1}{2} )\frac{1}{2}= \frac{17}{40}$
• Hence the 3 rational numbers are $\frac{7}{10},\frac{11}{40}$ and $\frac{17}{40}$
