Step-by-step explanation:

You can cancel out the 4! from the 10! leaving you with 5x6x7x8x9x10

Then you can cancel out 2 from 6 and the other 2 from 8

multiply the rest

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.
