Ответ:

Щоб знайти фальшиву монету серед шести монет за мінімальне число зважувань на шалькових терезах без гирьок, можна використати наступний спосіб:

Розділіть монети на дві групи по три монети в кожній.

Зважте дві групи монет. Якщо вага однакова, то фальшива монета знаходиться у третій групі, яка не брала участі у зважуванні.

Якщо вага неоднакова, то фальшива монета знаходиться у легшій групі.

Розділіть легшу групу на дві монети і зважте їх. Якщо вага однакова, то фальшива монета - це та, що не брала участі у зважуванні. Якщо вага неоднакова, то фальшива монета - це легша.

Таким чином, можна знайти фальшиву монету за два зважування.

1: I'm really interested in cars, so this was an amazing day for me. I still can't believe that my first driving experience was in a Lamborghini and an Aston Martin! I've got a video of the whole thing. I'm glad about that, because on the day there's no time to look at the cars properly. As soon as you finish, the next driver gets in. I was a bit
upset about that. Liam

I was very surprised to get this activity day for my birthday, but indoor skydiving was awesome I can't wait to go again. Before the activity, there are lots of hand signals to learn, so you can communicate when you're flying in the wind tunnel You can't speak in there! At first, I was worried about forgetting them, but it was fine. Jade

Текст 5:What a brilliant afternoon! First, there was a talk about the history of chocolate. Then it was time for the best bit-making and decorating our own chocolates!
