a fraction is less than 1. Choose a counterexample that will prove this conjecture false

Answer:
1st option
Step-by-step explanation:
Here we are trying to prove that not all fractions are less than 1. So we have to choose an example in which the fraction is more than 1.
1) [tex] \frac{8}{7} = 1 \frac{1}{7} [/tex]
This fraction is greater than 1 hence it can prove that the conjecture is false.
2) ½ is lesser than 1 and will not prove that the conjecture is false.
