[Question]On his farm, Mr. Valentino has 200 chickens, twice as many ducks as chickens and three times as many turkeys as ducks. How many birds does Mr. Valentino have on the farm in total?
[Answer]Mr. Valentino has twice as many ducks as chicken on his farm, which means there are 2 * 200 = 400 ducks on the farm. The number of turkeys is three times as many as the number of ducks on Mr. Valentino's farm, a total of 3 * 400 = 1200 turkeys. In total, Mr. Valentino has 1200 + 400 = 1600 ducks and turkeys on his farm. If you add the number of chickens on the farm, the number of birds on the farm becomes 1600 + 200 = 1800 birds. The answer is 1800.

[Question]If Buzz bought a pizza with 78 slices at a restaurant and then decided to share it with the waiter in the ratio of 5:8, with Buzz's ratio being 5, what's twenty less the number of slices of pizza that the waiter ate?
[Answer]The total ratio representing the slices of pizza that Buzz bought is 5 + 8 = 13. If he shared the slices of pizza with the waiter, the waiter received a fraction of 8 / 13 of the total number of slices, which totals 8 / 13 * 78 = 48 slices. Twenty less the number of slices of pizza that the waiter ate is 48 - 20 = 28. The answer is 28.
