Question

За первый час было расчищено от снега пять семнадцатых всей дороги, а за второй час-девять семнадцатых всей дороги.Какая часть дороги была расчищена от снега за эти два часа? На какую часть дороги было расчищено меньше в первый час чем во второй?

Answer 1

За первый час расчистили 5/17, за второй-9/17 следовательно за два часа  расчитстили 5+9/17=14/17. 

2)на 4/17 

Answer 2

Calculation of Cleared Road Sections

To calculate the portion of the road that was cleared of snow in the first two hours, we need to add the fractions of the road cleared in each hour.

According to the information provided, in the first hour, 5/17 of the road was cleared

In the second hour, 9/17 of the road was cleared.

To find the total portion of the road cleared in the first two hours, we add the fractions:

5/17 + 9/17 = 14/17

Therefore, 14/17 of the road was cleared of snow in the first two hours.

Comparison of Cleared Road Sections

To determine the difference in the portions of the road cleared in the first and second hours, we subtract the fraction cleared in the first hour from the fraction cleared in the second hour.

9/17 - 5/17 = 4/17

Therefore, 4/17 of the road was cleared less in the first hour compared to the second hour.

Please let me know if there's anything else I can help#### Calculation of the Cleared Road Fraction To determine the fraction of the road that was cleared of snow in the first two hours, we need to add the fractions cleared in the first and second hours.

The fraction cleared in the first hour is 5/17 of the entire road, as stated in the question.

The fraction cleared in the second hour is 9/17 of the entire road, as stated in the question.

To find the total fraction cleared in the first two hours, we add these two fractions together:

5/17 + 9/17 = 14/17

Therefore, 14/17 of the road was cleared of snow in the first two hours.

Comparison of Snow Clearance in the First and Second Hours

To determine the difference in the fraction of the road cleared in the first and second hours, we subtract the fraction cleared in the first hour from the fraction cleared in the second hour.

The fraction cleared in the first hour is 5/17 of the entire road, as stated in the question.

The fraction cleared in the second hour is 9/17 of the entire road, as stated in the question.

To find the difference, we subtract the fraction cleared in the first hour from the fraction cleared in the second hour:

9/17 - 5/17 = 4/17

Therefore, the fraction of the road that was cleared less in the first hour compared to the second hour is 4/17.

Problem Details

It is given that in the first hour, five seventeenths of the total road was cleared of snow. In the second hour, nine seventeenths of the total road was cleared of snow.

Calculating Portions Cleared

- Total road = 17 parts (denominator of fractions given) - In 1st hour: 5/17 parts were cleared - In 2nd hour: 9/17 parts were cleared - Total cleared in both hours = 5/17 + 9/17 = 14/17 parts

Comparing Hours

- In 1st hour: 5/17 parts were cleared - In 2nd hour: 9/17 parts were cleared - So less was cleared in the 1st hour (5/17) than the 2nd hour (9/17)

Therefore, the portion of the total road cleared in both hours is 14/17. The smaller portion was cleared in the first hour.
