Answer 1

Answer:

(a) , (c) is the answer of the pairs of equivalent rational number

Step-by-step explanation:

We know that if we need to know which of following equivalent rational we have to make them in simpleaset form :-

a) -8/3 ( this can not be done in simplest form)

25/5 ( 5/1 or 5 )

so this does not have equivalent rational

number because after cutting the answer will

be (-8/3 and 5)

c) similarly as the (a) answer

after cutting 2/5 and 4/7
