Answer 2

Ответ: 36 1/9

Пошаговое объяснение:

первое действие в скобках деление

5 2/3: 3 2/5= 17/3 * 5/17= 5/3= 1 2/3

второе действие в скобках минус

7 7/9 - 1 2/3= 6 7-6/9= 6 1/9

третье действие деление.

7,2 : 0,24 = 30.

четвёртое действие.

6 1/9 +30= 36 1/9

Answer 3

Let's break down the expression step by step:

1. Calculate each fraction:

   • 7 7/9 = 7 + 7/9 = 63/9 + 7/9 = 70/9
   • 5 2/3 = 5 + 2/3 = 15/3 + 2/3 = 17/3
   • 3 2/5 = 3 + 2/5 = 15/5 + 2/5 = 17/5

2. Perform the divisions:

   • (70/9 - 17/3) / (17/5) = [(70/9) * (5/17)] - [(17/3) * (5/17)] = (350/153) - (85/51)

3. Calculate the division result:

   • (350/153) - (85/51) = (350 * 51 - 85 * 153) / (153 * 51) = (17850 - 13005) / 7803 = 4845 / 7803

4. Calculate the decimal value:

   • 4845 / 7803 ≈ 0.6209723

5. Finally, add 7.2 and divide by 0.24:

   • (0.6209723 + 7.2) / 0.24 ≈ 30.2123858

So, the result of the given expression is approximately 30.2123858.
