Question

В среду уроки в 5 классе длились 3 1\3ч , а перемены -5\6 ч.Сколько времени пятикласники находились в школе ? Вырази ответ сначала в часах, а зтем в минутах.

Answer 1

3 1/3 + 5/6 = 10/3 + 5/6 = 20/6 + 5/6 = 25 / 6 = 4 1/6 часа = 4*60 + 10 = 250 минут

Answer 2

$3 \frac{1}{3} + \frac{5}{6} = \frac{10}{3} + \frac{5}{6} = \frac{20}{6} + \frac{5}{6} = \frac{25}{6} =4 \frac{1}{6}$ часа = 4*60+60/6=250 мин

Answer 3

Calculation of Time Spent in School

To calculate the total time spent in school by fifth-grade students, we need to add the duration of the lessons and the breaks together.

Given: - Lesson duration: 3 1/3 hours - Break duration: 5/6 hours

To find the total time spent in school, we add the lesson duration and the break duration:

3 1/3 hours + 5/6 hours

To add these fractions, we need to find a common denominator. The least common multiple of 3 and 6 is 6. Let's convert the fractions to have a common denominator:

3 1/3 hours = 3 hours + 1/3 hours = 3 hours + 2/6 hours = 3 hours + 2/6 hours = 3 hours + 1/6 hours

Now we can add the fractions:

3 hours + 1/6 hours + 5/6 hours

Adding the fractions:

3 hours + (1/6 + 5/6) hours = 3 hours + 6/6 hours = 3 hours + 1 hour = 4 hours

Therefore, fifth-grade students spent 4 hours in school.

To express this answer in minutes, we multiply the number of hours by 60 (since there are 60 minutes in an hour):

4 hours * 60 minutes/hour = 240 minutes

Therefore, fifth-grade students spent 240 minutes in school.

Please note that the above calculation assumes that the given durations are accurate and do not account for any additional factors that may affect the actual time spent in school.
