Question

2) (2,07 * 4 4/9 - 7,75) * 80 : 23,2

Answer 1

Ответ:

(2,07 * 4 4/9 - 7,75) * 80 : 23,2 = 5

Пошаговое объяснение:

1) 2,07 * 4 4/9 = 207/100 * 40/9 = (23*2)/(5*1) = 46/5 = 9,2

2) 9,2 - 7,75 = 1,45

3) 1,45 * 80 = 116

4) 116 : 23,2 = 5

Answer 2

To solve the given expression step by step:

1. $2.07 \times \left(4 \frac{4}{9}\right)$ $= 2.07 \times \left(4 + \frac{4}{9}\right)$ $= 2.07 \times \left(\frac{36}{9} + \frac{4}{9}\right)$ $= 2.07 \times \frac{40}{9}$ $= 9.2$

2. $9.2 - 7.75$ $= 1.45$

3. $(1.45 \times 80) / 23.2$ $= 116 / 23.2$ $= 5$

So, the result of the given expression is $5$.
