Question

Длина тюленя в 11 раз меньше, чем длина синего кита. Синий кит на 30 м длиннее тюленя. Чему равна длина длина каждого из этих животных? (надо решение по действиям)

Answer 1

1) 11-1=10(частей) -приходится на 30 м
2) 30:10=3(М) тюлень
3) 3*11=33(м) кит

Answer 2

Calculating the Length of the Blue Whale and Seal

To find the length of each of these animals, we can use the information provided in the question and solve for the lengths of the blue whale and the seal.

Given: - The length of the blue whale is 30 meters longer than the seal. - The length of the seal is 11 times smaller than the blue whale.

Let's denote: - Length of the seal as S - Length of the blue whale as B

We can express the relationship between the lengths of the blue whale and the seal as: 1. B = S + 30 (The length of the blue whale is 30 meters longer than the seal) 2. S = 1/11 * B (The length of the seal is 11 times smaller than the blue whale)

Solving for the Lengths

We can solve these equations to find the lengths of the blue whale and the seal.

Substituting the value of S from equation 2 into equation 1: B = (1/11 * B) + 30

Multiplying through by 11 to clear the fraction: 11B = B + 330

Subtracting B from both sides: 10B = 330

Dividing by 10: B = 33

Substituting the value of B back into equation 1: S = 33 - 30 S = 3

Conclusion

The length of the blue whale is 33 meters, and the length of the seal is 3 meters.
