Answer 1

This can help you. First find the l.c.m and then multiply

Answer 2

$\textsf{\underline{\underline{SOLUTION:-}}}$

${\texttt{\underline{\underline{4th question's (a):-}}}}$

Rational numbers between these 2 numbers

$\frac{3}{5} \: and \: \frac{7}{8}$

LET US USE THE FORMULA

$\frac{a + b}{2}$

"THIS FORMULA IS USED TO FIND THE RATIONAL NUMBERS BETWEEN THE RATIONAL NUMBERS"

So , now coming to our problem,

$\frac{ \frac{3}{5} + \frac{7}{8} }{2}$

$\frac{ \frac{59}{40} }{2}$

$\frac{59}{80}$

This is the 1st number between

$\frac{3}{5} \: and \: \frac{7}{8}$

Now the other number between

$\frac{3}{5} \: and \: \frac{59}{80}$

$\frac{107}{160}$

Here we used same formula as above.

Now the 3rd number between

$\frac{3}{5} \: and \: \frac{107}{160}$

$\frac{203}{320}$

$\textsf{\underline{\underline{2nd part in 4th question:-}}}$

There will be infinite rational numbers between any 2 rational numbers.

$\huge{\texttt{5th question:-}}$

4 RATIONAL NUMBERS BETWEEN

$\frac{3}{7} \: and \: \frac{5}{7}$

$= \frac{4}{7}$

Rational number between

$\frac{3}{7 \:} and \: \frac{4}{7}$

$= \frac{1}{2}$

Rational number between

$\frac{3}{7} \: and \: \frac{1}{2}$

$= \frac{13}{28}$

Rational number between

$\frac{3}{7} \: and \: \frac{13}{28}$

$= \frac{25}{56}$
