Answer 1

Answer:

(A)

90

36

=

15

6

=

5

2

130

52

=

65

26

=

13×5

13×2

=

5

2

∴

90

36

&

130

52

are equivalent rational numbers.

(B)

24

−15

=

8

−5

−72

−45

=

24

15

=

8

5

∴

24

−15

&

−72

−45

are not eqivalent rational numbers.

Answer 2

(A)

90

36

=

15

6

=

5

2

130

52

=

65

26

=

13×5

13×2

=

5

2

∴

90

36

&

130

52

are equivalent rational numbers.

(B)

24

−15

=

8

−5

−72

−45

=

24

15

=

8

5

∴

24

−15

&

−72

−45

are not eqivalent rational numbers.

(C)

36

−11

and

72

22

Again since there signs are different , they are not equivalent rational numbers.
