Can you tell what these cats are feeling?
Ever wonder what cats are thinking? Some people don’t need to guess—they seemed to be able to tell just by looking at cats’ faces!
Cats use facial expressions to communicate how they’re feeling, much like humans do. A Canadian study used short YouTube videos to test people’s ability to read the animals’ expressions. The study had more than 6,000 participants. About 13 percent seemed to read the majority of the cats’ expressions correctly after looking at each clip for just a few seconds!
Researchers gathered 40 cat videos. Out of those, 20 showed cats that appeared to be happy.
Write a fraction that represents the number of happy cat videos.
<p>A number that stands for part of a whole. Fractions are typically written in the form of two numbers separated by a slash, such as “1/8.” This fraction is pronounced “one-eighth.” </p> <p><b>Example: </b>If an apple is cut into 4 equal slices, and you eat one slice, you have eaten 1/4 of an apple.</p>
