Question

(10¾-12:1⅕)*4/9+2⅙+3¼:5⅕​

Answer 1

Напиши все вот так вот, это вроде легкая задача

Answer 2

Ответ:

3 1/8 или 3,125

Пошаговое объяснение:

(10 3/4 - 12 : 1 1/5) * 4/9 + 2 1/6 + 3 1/4 : 5 1/5

сначала посчитаем в скобках

(10 3/4 - 12/1 : 6/5) = (10 3/4 - 12/1 * 5/6) = (10 3/4 - 60/6) = 10 3/4 - 10) = 3/4

получаем выражение

3/4 * 4/9 + 2 1/6 + 3 1/4 : 5 1/5

далее выполняем умножение

3/4 * 4/9 = 1/3

потом выполняем деление

3 1/4 : 5 1/5 = 13/4 : 26/5 = 13/4 * 5/26 = 5/8

теперь всё складываем

1/3 + 2 1/6 + 5/8 = 1/3 + 13/6 + 5/8 = 8/24 + 52/24 + 15/24 = 75/24 = 25/8 =

3 1/8 или 3,125

Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, we don't have any parentheses or exponents, so we can proceed with multiplication, division, addition, and subtraction from left to right:

1. First, perform the multiplication and division from left to right:

   (10¾ - 12:1⅕) * 4/9 + 2⅙ + 3¼:5⅕

   Start with the division:

   (10¾ - 12 * 5/6) * 4/9 + 2⅙ + 3¼:5⅕

   Now, perform the multiplication:

   (10¾ - 10) * 4/9 + 2⅙ + 3¼:5⅕

2. Next, perform the subtraction:

   (10¾ - 10) = ¾

   So, the expression becomes:

   (¾) * 4/9 + 2⅙ + 3¼:5⅕

3. Now, perform the multiplication:

   (¾) * (4/9) = (3/4) * (4/9) = 12/36 = 1/3

   The expression becomes:

   (1/3) + 2⅙ + 3¼:5⅕

4. Finally, perform the addition and division:

   (1/3) + 2⅙ = (1/3) + (13/6) = (2/6) + (13/6) = 15/6

   And:

   3¼:5⅕ = (13/4) / (26/5) = (13/4) * (5/26) = (13/52)

   Now, the expression is:

   (15/6) + (13/52)

5. You can simplify this further by finding a common denominator:

   To find a common denominator, multiply 6 by 13 and 52 by 1:

   (15/6) + (13/52) = (130/52) + (13/52)

   Now, they have the same denominator, so you can add them:

   (130/52) + (13/52) = (130 + 13) / 52 = 143/52

6. Finally, simplify the fraction if necessary:

   143/52 is already in its simplest form, but you can also express it as a mixed number if you prefer:

   143/52 = 2⅛

So, the result of the expression is either 143/52 or 2⅛.
