Question

За первый час было расчищено от снега 5/17 всей дороги, а за второй час 9/17 всей дороги. Какая часть дорогт была расчищена от снега за эти два часа? На какую часть дороги было расчищено меньше в первый час, чем во второй?

Answer 1

5/17+9/17=14/17 - расчищено от снега за два часа, 9/17-5/17=4/17 - на 4/17 расчищено меньше в первый час, чем во второй

Answer 2

Calculation of Snow Removal on the Road

To calculate the portion of the road that was cleared of snow in the first two hours, we need to determine the fraction of the road cleared in each hour and then add them together.

According to the given information, 5/17 of the entire road was cleared in the first hour, and 9/17 of the entire road was cleared in the second hour.

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 entire road was cleared of snow in the first two hours.

Comparison of Snow Removal in the First and Second Hours

To determine the difference in the portion 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 portion of the road cleared in the first hour is 5/17, and the portion cleared in the second hour is 9/17.

To find the difference, we subtract:

9/17 - 5/17 = 4/17

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