List five rational numbers between $\frac{2}{8}$ and $\frac{8}{3.}$

Answer:_______________

List five rational numbers between $\frac{4}{10}$ and $\frac{8}{4.}$

Answer: $\frac{17}{40}$ , $\frac{18}{40}$ , $\frac{19}{40}$ , $\frac{20}{40}$ , $\frac{21}{40}$

SOLUTION 1 :

Soln :

Let us first written the given rational numbers with the same denominators.

Now , $\frac{4}{10}$ = $\frac{4}{10}$ x $\frac{4}{4}$ = $\frac{16}{40}$

and. $\frac{8}{4}$ = $\frac{8}{4}$ x $\frac{10}{10}$ = $\frac{80}{40}$

$\frac{17}{40}$ , $\frac{18}{40}$ , $\frac{19}{40}$ , $\frac{20}{40}$ , $\frac{21}{40}$ are the five required rational numbers.

List five rational numbers between $\frac{3}{6}$ and $\frac{7}{7.}$

SOLUTION 1 :

Soln :

Let us first written the given rational numbers with the same denominators.

Now , $\frac{3}{6}$ = $\frac{3}{6}$ x $\frac{7}{7}$ = $\frac{21}{42}$

and. $\frac{7}{7}$ = $\frac{7}{7}$ x $\frac{6}{6}$ = $\frac{42}{42}$

$\frac{22}{42}$ , $\frac{23}{42}$ , $\frac{24}{42}$ , $\frac{25}{42}$ , $\frac{26}{42}$ are the five required rational numbers.
