Упростите выражение 4цел.2/3 К - К+ 1цел1/12 К и найдите его значение при к = 8/19 В овощехранилище привезли 320т овощей. 75% привезенных овощей составлял картофель, а 11/16 остатка – капуста. Сколько тонн капусты привезли в овощехранилище?

Answer 1

Последняя задача. По-моему так- выразим проценты получим в итоге 60. 320-60=260(картофель) 60( капуста) не уверена

Answer 2

Calculations and Simplifications

a) To find the product of 3/7 and 5/11: - The result is 15/77. - The calculation is: 3/7 * 5/11 = 15/77 [[1]].

b) To find the product of 6/25 and 5/18: - The result is 5/30, which simplifies to 1/6. - The calculation is: 6/25 * 5/18 = 5/30 = 1/6 [[2]].

c) To find the product of 2 1/10 and 1 1/14: - The result is 2 1/140. - The calculation is: 2 1/10 * 1 1/14 = 2 1/140 [[3]].

d) To find the product of 3 3/5 and 1 1/9: - The result is 3 3/45, which simplifies to 3 1/15. - The calculation is: 3 3/5 * 1 1/9 = 3 3/45 = 3 1/15 [[4]].

Additional Calculations

a) The expression 1 5/17 * (7 - 2 4/11): - The result is 6 3/17. - The calculation is: 1 5/17 * (7 - 2 4/11) = 6 3/17.

b) The expression (4.2 ÷ 1.2 + 1.05) * 1.6: - The result is approximately 14.7. - The calculation is: (4.2 ÷ 1.2 + 1.05) * 1.6 ≈ 14.7.

Word Problem

In one bag, 2 4/5 kg of wheat was poured, and in another bag, 6/7 of this quantity was poured. The difference in the amount of wheat poured into the second bag compared to the first bag is: - The difference is 1 3/35 kg. - The calculation is: 2 4/5 - (2 4/5 * 6/7) = 1 3/35.

Simplification and Value Calculation

Simplify the expression 4 2/3 K - K + 1 1/12 K and find its value when K = 8/19: - The simplified expression is 4 1/3 K - K. - When K = 8/19, the value of the expression is approximately 2 1/19.

Vegetable Storage Problem

In a vegetable storage, 320 tons of vegetables were delivered. 75% of the delivered vegetables were potatoes, and 11/16 of the remainder was cabbage. The amount of cabbage delivered to the vegetable storage is: - The amount of cabbage delivered is 110 tons. - The calculation is: 320 * (1 - 0.75) * (11/16) = 110 [[5]].
