Question

1}В двух стопках 54 тетради.Сольо тетрадей в каждой стопке если в первой стопе в 2 раза меньше тетрадей чем во второй2}В первой связе на 56 шаров больше чем во второй.Сколько шаров в каждой связке если во второй связке в 5 раз меньше шаров чем в первой3}За 6 одинаковых машинок заплатили 72 рублей а за 4 одинаковых куклы 96 руб.Во соко раз цена машинки меньше чем цена куклы

Answer 1

1)Пусть в первой-х, во второй-2хВсего-54
х+2х=54
3х=54
х=18 тетрадей-в первой стопке
18*2=36 тетрадей-во второй стопке

2)В первой связке-х+56 шаров, во второй-х шаров
х+56=5х
х-5х=-56
-4х=-56
х=14 шаров-во второй связке
14+56=70 шаров-в первой связке

3)72:6=9 р -стоит 1 машинка
96:4=24 р -стоит 1кукла
24:9=2 2/3
Ответ: в 2 2/3 раза машинка стоит дешевле, чем кукла

Answer 2

Task 1: Number of Notebooks in Each Stack

In two stacks, there are a total of 54 notebooks. The number of notebooks in the first stack is twice as less as the number of notebooks in the second stack.

To find the number of notebooks in each stack, we can set up the following equation:

Let x be the number of notebooks in the second stack. The number of notebooks in the first stack would be x/2.

The equation can be written as: x + x/2 = 54

To solve this equation, we can multiply both sides by 2 to eliminate the fraction: 2x + x = 108 3x = 108 x = 36

Therefore, there are 36 notebooks in the second stack, and 18 notebooks in the first stack.

Task 2: Number of Balls in Each Bundle

In the first bundle, there are 56 more balls than in the second bundle. The number of balls in the second bundle is 5 times less than the number of balls in the first bundle.

To find the number of balls in each bundle, we can set up the following equation:

Let x be the number of balls in the second bundle. The number of balls in the first bundle would be x + 56.

The equation can be written as: x + 56 = 5x

To solve this equation, we can subtract x from both sides: 56 = 4x

Dividing both sides by 4, we get: x = 14

Therefore, there are 14 balls in the second bundle, and 70 balls in the first bundle.

Task 3: Price Difference between a Toy Car and a Doll

For 6 identical toy cars, the total cost is 72 rubles. For 4 identical dolls, the total cost is 96 rubles. The price of a toy car is less than the price of a doll.

To find the price difference between a toy car and a doll, we can divide the total cost of each by the respective quantities:

Price of a toy car = 72 rubles / 6 cars = 12 rubles per car Price of a doll = 96 rubles / 4 dolls = 24 rubles per doll

Therefore, the price of a toy car is 12 rubles less than the price of a doll.
