Question

Seven Equivalent Rational Numbers 109/9

Answer 1

Step-by-step explanation:

Equivalent rational numbers by multiplication:

If

a

b

is a rational number and m is a non-zero integer then

a×m

b×m

is a rational number equivalent to

a

b

.

For example, rational numbers

12

15

,

20

25

,

−28

−35

,

−48

−60

are equivalent to the rational number

4

5

.

We know that if we multiply the numerator and denominator of a fraction by the same positive integer, the value of the fraction does not change.

For example, the fractions

3

7

and

21

49

are equal because the numerator and the denominator of

21

49

can be obtained by multiplying each of the numerator and denominator of

3

7

by 7.
