of a room with 3/4 of a roll of wire.

We are now going to cross multiply. By cross-multiplting, you would get:

You are now going to divide both numbers by 3 in order to get the x by itself.

By dividing, you get:

Therefore, the answer is 1/4.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
