what fraction of the carnival is dunk tanks and games?

the fraction of the carnival with dunk tanks and game is__

PART B
how much greater is the part of the carnival with student exhibits that the one with games? explain how you could use a model to find the answer

To find the fraction, you add the dunk tanks and games together. This is because you want to know what fraction of them combined, so it is 1/10 + 4/10, the given fractions of the games. Because these already share a common denominator, you would add the numerators, but the denominators stay the same, meaning the answer is 5/10.

PART B:

You know that the games make up 4/10 of the carnival, and student exhibits 5/10 of the carnival. Because they have the same denominator, you can subtract the fractions. You want to know the difference, so you do 5/10 - 4/10. This gives you the answer of 1/10. You could use a model to find the answer by making a bar graph. You can compare the bars of the sections you are looking at, and you can see the difference.
