To determine the amount of pizza that Marissa and her friends ate, we can represent the total number of pizzas they had and the amount they ate as fractions.

Marissa and her friends had 3 pizzas, each with 8 slices. Therefore, the total number of slices they had is 3 x 8 = 24 slices.

They ate 2 1/4 of the pizzas, which can be written as a mixed fraction. To convert the mixed fraction to an improper fraction, we multiply the whole number by the denominator and add the numerator.

So, 2 1/4 can be converted to (2 x 4 + 1)/4 = 9/4.

Now, we can compare the amount they ate (9/4) to the total number of slices (24).

To find out how much of the pizza is left uneaten, we subtract the amount they ate from the total amount: 24 - 9/4.

To find a common denominator between 4 and 24, we observe that 4 x 6 = 24. So, we need to express 24 as a fraction with a denominator of 4: 24/4 = 6.

Now we can subtract the fractions: 24/4 - 9/4 = 15/4.

Therefore, Marissa and her friends ate 15/4 or 3 3/4 of the pizzas.

To visually represent the amount of pizza they ate, we can imagine the 3 pizzas with 8 slices each.

Since 1 pizza (8 slices) is equal to 4/4, Marissa and her friends ate 3 pizzas plus an additional 3/4 of a pizza.

To represent this visually, we can draw 3 pizzas, each having 8 slices, and shade in 3/4 of another pizza.

Here is a rough visual representation of the amount of pizza they ate:

In the diagram above, the first 3 pizzas are completely filled, representing the 3 whole pizzas they ate. The fourth pizza is shaded to show the 3/4 portion that they consumed.
