Answer 2

Answer:

$(2,3),(3,4),(5,7),(9,11)$

Step-by-step explanation:

• As per the data given in the question, we need to give four examples of co primes

• As we know, co primes are the numbers that have only one common factor

For example:

• All prime numbers are co prime to each other because they have only one common factor

Ex: $2,3,5,7,11...$

• All consecutive numbers are co prime to each other

Ex: $(1,2), (3,4), (4,5),...$

Hence, four examples of pairs of co primes are $(2,3),(3,4),(5,7),(9,11)$.
