Question

шнур длиной 15м разрезали на 3 равные части. На сколько таких же частей можно разрезать шнур длиной 40м?

Answer 1

15 :3  = 5 (см)  - в 1-ой части
40 : 5  = 8(ч)
Ответ: на 8 частей

Answer 2

Calculating the Number of Equal Parts

To calculate the number of equal parts a 40m cord can be cut into, given that a 15m cord was cut into 3 equal parts, we can use the following approach:

1. Calculate the Length of Each Part: First, we calculate the length of each part when a 15m cord is cut into 3 equal parts. 2. Use the Length of Each Part to Calculate the Number of Parts for a 40m Cord: Then, we use the length of each part from the 15m cord to determine how many equal parts a 40m cord can be cut into.

Calculation

- Length of Each Part from the 15m Cord: When a 15m cord is cut into 3 equal parts, each part is 15m / 3 = 5m long. - Number of Equal Parts for a 40m Cord: To find out how many equal parts a 40m cord can be cut into using the length of each part from the 15m cord, we divide the total length of the 40m cord by the length of each part from the 15m cord: 40m / 5m = 8.

So, a 40m cord can be cut into 8 equal parts using the same length as the parts from the 15m cord.
