Question

Таня подсчитала, что 1/6 всего времени , которое потребовалось ей для выполнения д/ з у неё ушло на математику, а 1/4- на русский. Остальные уроки она сделала за 1 ч 10 мин. Сколько времени Таня выполняла д/ з?

Answer 1

1/6+1/4=3/12+2/12=5/12 (ушло на математику и русский)
12/12-5/12=7/12 (составил 1ч 10 мин)
70*12/12:7/12= 840/7=120 минут
120 минут = 2 часа
Ответ : 2 часа

Answer 2

1)1/6+1/4=5/12(времени)-делала математику и русский
2)1-5/12=7/12(времени)-делала остальные уроки
3)70/7/12=120(минут)-делала дз

Answer 3

Task: Calculate the time Tanya spent on her homework

To calculate the time Tanya spent on her homework, we need to determine the time she spent on math and Russian, and then subtract that from the total time she spent on all her subjects.

Let's break down the information given:

- Tanya spent 1/6 of the total time on math. - Tanya spent 1/4 of the total time on Russian. - The remaining subjects were completed in 1 hour and 10 minutes.

To calculate the time Tanya spent on math, we need to find 1/6 of the total time. Similarly, to calculate the time she spent on Russian, we need to find 1/4 of the total time.

Let's calculate the time Tanya spent on math and Russian:

- Time spent on math: 1/6 of the total time - Time spent on Russian: 1/4 of the total time

To find the total time, we need to add the time spent on math, Russian, and the time spent on the remaining subjects.

Now, let's calculate the time Tanya spent on her homework.
