Question

Решите эти 2 задачи!!! В зале кинотеатра 180 мест. Занято три четверти мест. Сколько мест в зале ще не занято? Пять девятых завезёных в магазин товаров - бананы, а две девятых - апельсины. Сколько килограммов бананов завезли в магазин, если апельсинов завезли 126 кг

Answer 1

Ответственным:

Пошаговое объяснение:

1.

1) 180 * 3/4 = 45*3 / 1 = 135/1 = 135 (мест) - занято

2) 180 - 135 = 45 (мест) - не занято

2.

1) 5/9 + 2/9 = 7/9 - апельсины и бананы

2) 1 - 7/9 = 9/9 - 7/9 = 2/9 - остальные фрукты

3) 126 : 2/9 = 126 * 9/2 = 63*9 / 1 = 567 (кг) - вес всех фруктов завезённых в магазин

4) 567 * 5/9 = 63*5 / 1 = 315/1 = 315 (кг) - привезли бананов

Ответ : 315 кг

Answer 2

Problem 1: Number of Unoccupied Seats in a Movie Theater

In a movie theater with 180 seats, three-quarters of the seats are already occupied. We need to determine how many seats are still unoccupied.

To solve this problem, we can use the following steps:

1. Calculate the number of occupied seats by multiplying the total number of seats by three-quarters (0.75). 2. Subtract the number of occupied seats from the total number of seats to find the number of unoccupied seats.

Let's apply these steps to the given problem:

1. Calculate the number of occupied seats: 180 * 0.75 = 135. 2. Subtract the number of occupied seats from the total number of seats: 180 - 135 = 45.

Therefore, there are 45 seats in the theater that are still unoccupied.

Problem 2: Weight of Bananas Delivered to the Store

In a store, five-ninths of the delivered goods are bananas, while two-ninths are oranges. We need to determine the weight of the bananas delivered to the store, given that 126 kg of oranges were delivered.

To solve this problem, we can use the following steps:

1. Calculate the weight of oranges as a fraction of the total weight of delivered goods. 2. Calculate the weight of bananas using the weight of oranges and the ratio of bananas to oranges.

Let's apply these steps to the given problem:

1. Calculate the weight of oranges: 126 kg. 2. Calculate the weight of bananas using the ratio of bananas to oranges: (5/9) * (total weight - weight of oranges).

- The total weight of delivered goods can be represented by the sum of the weights of bananas and oranges. - Let's assume the total weight of delivered goods is represented by "x" kg.

The equation becomes: (5/9) * (x - 126) = weight of bananas.

To find the weight of bananas, we need to solve this equation. However, we don't have enough information to determine the exact weight of bananas without knowing the total weight of delivered goods.

Please provide the total weight of delivered goods, and we can calculate the weight of bananas accordingly.
