Question

3 3/5•(-2 7/9) Допоможіть

Answer 1

Ответ:

$3 \frac{ 3}{5} \times ( - 2 \frac{7}{9} ) = \frac{18}{5} \times ( - \frac{25}{9} ) = - 10$

Мы 18 сокращаем с 9( зачёркиваем), там где 9 ставим 1, там где 18 пишем 2. Теперь 25 сокращаем с 5( зачёркиваем), там где 25 пишем 5, там где 5 пишем 1. 2×5=10, так как у 25/9 есть минус = -10.

Answer 2

Ответ:

$3\frac{3}{5} *(-2\frac{7}{9} )=-(\frac{18*25}{5*9})=-(2*5)=-10$

Answer 3

Calculation of 3 + 3/5 • (-2 + 7/9)

To calculate the expression 3 + 3/5 • (-2 + 7/9), we can follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's simplify the expression inside the parentheses: - (-2 + 7/9) = -2 + 7/9 = -18/9 + 7/9 = -11/9

Now, we can substitute this value back into the original expression: 3 + 3/5 • (-11/9)

Next, we can perform the multiplication: 3/5 • (-11/9) = -33/45

Finally, we can add this result to 3: 3 + (-33/45) = 135/45 + (-33/45) = (135 - 33)/45 = 102/45

So, the value of the expression 3 + 3/5 • (-2 + 7/9) is 102/45.
