Beside a prehistoric river, Emek and Luna searched for dinosaur footprints. They found three kinds and recorded each count on a bar graph. The graph showed 12 three-toed tracks, 7 wide tracks, and 4 small tracks. Emek saw that the three-toed tracks appeared most often, while the small tracks appeared least often. Most three-toed tracks pointed toward a muddy bend in the river. Using their data, they chose to search there and soon discovered another trail of footprints.

Hint
Compare the three counts and find the greatest number.
Emek and Luna's bar graph showed 12 three-toed tracks, 7 wide tracks, and 4 small tracks. Which kind of track appeared most often?
Wide tracksSmall tracksThree-toed tracksWide tracks and small tracks appeared equally oftenCorrect! 12 is the greatest count, so three-toed tracks appeared most often.
Try again. Compare 12, 7, and 4 and choose the kind with the greatest count.
Next🎉 Congrats! You got this question!
Hint
Find the difference between 12 and 7.
The bar graph showed 12 three-toed tracks and 7 wide tracks. How many more three-toed tracks than wide tracks did Emek and Luna find?
Correct! They found 5 more three-toed tracks than wide tracks.
Try again. Subtract the smaller count from the larger count.

Hint
The kind with the greatest number of recorded tracks is most likely to be chosen.
Suppose Emek chooses one of the 23 recorded tracks without looking. Based on the bar graph, which kind of track is he most likely to choose?
Small trackThree-toed trackWide trackAll three kinds are equally likelyCorrect! There are more three-toed tracks than either of the other kinds, so a three-toed track is most likely.
Try again. Compare how many tracks of each kind were recorded.
