(1.25+5/24)*4.8-(-5/13)*(3/5+2) (/-черта дроби, *-знак умножения)

Answer 1

Ответ:5.65 (округляя 5.7)

Пошаговое объяснение: (1.25+ 5/24)*4.8-(-5/13)*(3/5+2)

1)1.25+0.2= 1.45

2)0.6+2=2.6

3)-5/13= -0.4

4)1.45*4.8-0.4*2.6 = 6.69 - 1.04 = 5.65 (округляя 5.7)

Answer 3

To evaluate the expression (1.25 + 5/24) * 4.8 - (-5/13) * (3/5 + 2), let's break it down step by step:

First, let's simplify the expression within the parentheses (3/5 + 2): 3/5 + 2 = (3/5) + (10/5) = 13/5

Now we can substitute this back into the main expression: (1.25 + 5/24) * 4.8 - (-5/13) * (13/5)

Next, let's simplify the expression within the first parentheses (1.25 + 5/24): 1.25 + 5/24 = (30/24 + 5/24) = 35/24

Now we can substitute this back into the main expression: (35/24) * 4.8 - (-5/13) * (13/5)

Now let's simplify the expression within the second parentheses (-5/13 * 13/5): (-5/13) * (13/5) = (-65/65) = -1

Now we can substitute this back into the main expression: (35/24) * 4.8 - (-1)

Next, let's simplify the first part of the expression (35/24 * 4.8): (35/24) * 4.8 = (35/24) * (24/5) = 35/5 = 7

Now we can substitute this back into the main expression: 7 - (-1)

Finally, we can simplify the expression: 7 - (-1) = 7 + 1 = 8

Therefore, the value of the expression (1.25 + 5/24) * 4.8 - (-5/13) * (3/5 + 2) is 8.
