Question

find 4 rational between 2/5 and 3/4

Answer 1

9/20,10/20,11/20,12/20,13/20

Answer 2

[ Here, the first thing is to bring their dinominators equal ]

$\frac{2}{5} = \frac{2 \times 4}{5 \times 4} = \frac{8}{20}$

$\frac{3}{4} = \frac{3 \times 5}{4 \times 5} = \frac{15}{20}$

[ now, look at both the numbers. We have 4 rational numbers between them]

♦ Four rational numbers between them are

$\frac{9}{20} \: \frac{10}{20} \: \frac{11}{20} \: \frac{12}{20}$
