i)-4/10 ,-6/15,-8/20

ii)6/14,9/21,12/28

Answer 2

Answer:

a)The equivalent rational numbers of 2/-3 are,

       1) ( 2/-3 ) × (2/2) = 4/-6

       2)( 2/-3 ) × (3/3) = 6/-9

       3)( 2/-3 ) × (4/4) = 8/-12

b)The equivalent rational numbers of 4/5 are,

       1) ( 4/5 ) × (2/2) = 8/10

       2)( 4/5 ) × (3/3) = 12/15

       3)( 4/5 ) × (4/4) = 16/20  

Step-by-step explanation:

To find the equivalent fractions, multiply both numerator and denominator of the original fraction by same number.

a) To find 3 equivalent rational numbers of 2/-3,

       1) ( 2/-3 ) × (2/2) = 4/-6

       2)( 2/-3 ) × (3/3) = 6/-9

       3)( 2/-3 ) × (4/4) = 8/-12

b) To find 3 equivalent rational numbers of 4/5,

       1) ( 4/5 ) × (2/2) = 8/10

       2)( 4/5 ) × (3/3) = 12/15

       3)( 4/5 ) × (4/4) = 16/20
