Question

find five rational numbers between a. 1/4and3/4 b. 2/7and5/7​

Answer 1

Answer:

the molecular masses is expressed as

Answer 2

$\frac{1}{4} = \frac{1 \times 5 + 1}{4 \times 5 + 1} = \frac{6 }{20}$

$\frac{3}{4} = \frac{3 \times 5 + 1}{4 \times 5 + 1} = \frac{18}{20}$

the 5 rational no is

$\frac{4}{10} \: \: \frac{5}{10} \: \: \frac{6}{10} \: \: \frac{7}{10} \: \: \frac{8}{10}$

so do the same process as done above
