There are 3 things possibly at play here.
Are you trying to make decisions about the same question? If the top score in a game is currently 87 out of 100, and the last player takes their turn. The announcer says the player scored "Ninety...." they won. It doesn't matter if the complete information is "Ninety-five", "Ninety-nine" or even "Ninety... just flat ninety" ... the final player is the winner. You dont need the second digit. Knowing the score is in the range of 90-99 isn't COMPLETE information, but it is ENOUGH information... To answer "did this player win" ... if you wanted to know if they beat the world record score of 97, then you'd need the second digit. You only need fully complete information if you need a fully complete answer.
Another option is that you already have complete information. "I tossed a coin 10 times and 8 times it landed on heads" -- what happened the other 2 times? You already know. Just because no one said it doesnt mean you don't have it. Not everything needs to be said explicitly for it to be true. "There's 2 types of people in the world: those that can derive missing data."
The third option is just that it truly doesn't matter, usually because of the rule of the first point. How long it takes to get to the destination, whether 3 hours or 4 hours, or 3.5 hours... doesnt matter if the destination closes in 2 hours. "More than 2" is complete enough. Some things are ok with vague answers because the question was vague. Someone may have said "how long does it take to get there" but that truly doesnt matter, because the secret real question was "Can we arrive before the store closes"
