Eight out of nine kilogram peanuts can extract one out of three kilogram oil, and one kilogram peanuts can extract () kilogram oil

Eight out of nine kilogram peanuts can extract one out of three kilogram oil, and one kilogram peanuts can extract () kilogram oil

1 / 3 △ 8 / 9 = 3 / 8 (kg)
8 / 9 of a kilogram of peanuts can extract 1 / 3 of a kilogram of oil, and 1 kilogram of peanuts can extract 3 / 8 of a kilogram of oil

With 20kg peanut kernel, 8kg oil can be extracted. According to this calculation, how many tons of oil can be extracted from 100t peanut kernel? How many tons of peanut kernels do you need to extract 5 tons of oil? (answer with proportional knowledge)

(1) Suppose 100 tons of peanut can extract x tons of oil, 8:20 = x: 100, & nbsp; & nbsp; 20x = 100 × 8, & nbsp; & nbsp; X = 100 × 820, & nbsp; & nbsp; X = 40; a: 100 tons of peanut can extract 40 tons of oil. (2) to extract 5 tons of oil, you need y tons of peanut, 8:20 = 5: y, & nbsp
