Question

В трех коробках лежит 132 карандаша, причем во второй коробке их в 1,5 раза больше, чем в первой, а в третьей - в 4 раза меньше, чем в первой. Сколько карандашей лежит в первой коробке? а)24 б)36 в)48 г)другой ответ Помогите пожалуйста, срочно с решением Заранее спасибо

Answer 1

1- ая -?
2 -ая -? 1,5 раза Б ,чем в 1- ой
3- ая ? в 4 раза М, чем в 1-ой 
132 всего
Пусть х-   1 -яя коробка карандашей
Тогда1,5 х- 2 ая коробка каранашей
х/4-  3 ая 
 Уравнение.
х+1,5х+х/4=132
2,5х+0,25х=132
2,75х=132
х=132:2,75
х= 48
получается вариант ответа 48 г.

Answer 2

Problem Analysis

We are given three boxes of pencils, with the following information: - The second box contains 1.5 times more pencils than the first box. - The third box contains 4 times fewer pencils than the first box.

We need to determine the number of pencils in the first box.

Solution

Let's assume the number of pencils in the first box is x.

According to the given information: - The second box contains 1.5 times more pencils than the first box, so it contains 1.5x pencils. - The third box contains 4 times fewer pencils than the first box, so it contains x/4 pencils.

The total number of pencils in all three boxes is given as 132.

Therefore, we can write the equation: x + 1.5x + x/4 = 132

To solve this equation, we can combine like terms and solve for x.

Calculation

Let's solve the equation to find the value of x:

x + 1.5x + x/4 = 132

Combining like terms: 2.75x + x/4 = 132

Multiplying both sides by 4 to eliminate the fraction: 11x + x = 528

Combining like terms: 12x = 528

Dividing both sides by 12: x = 528/12 = 44

Therefore, the number of pencils in the first box is 44.

Answer

The number of pencils in the first box is 44.
