Step-by-step explanation:
Making the same denominator of the rational numbers
5
4
and
3
2
.
5
4
=
5×3
4×3
=
15
12
3
2
=
3×5
2×5
=
15
10
The rational numbers between
15
12
and
15
10
is,
2
15
12
+
15
10
=
30
22
So,
15
10
<
30
22
<
15
12
The rational number between
15
10
and
30
22
is,
2
15
10
+
30
22
=
30×2
42
=
30
21
The rational number between
15
12
and
30
22
is,
2
15
12
+
30
22
=
30×2
46
=
30
23
Thus,
15
10
<
30
21
<
30
22
<
30
23
<
15
12
.
Therefore the three rational numbers are
30
21
,
30
22
,
30
23
.
