Question

4 х 300 - 12 / 9 + 3

Answer 1

4×300-12/9 +3= 1 200-12/9+9/3. 3- превращаем в дробь, 3=9/3. Далее находим общий знаменатель 12/9 и 9/3 это 9. После этого 36/9 пишем как 4, 27/9 как 3.
1 200-36/9+27/9=1 200-4+3=1 199.
Ответ: 1 199

Answer 2

To solve the expression, follow the order of operations, which is commonly remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). The order is as follows:

1. Parentheses (if any)
2. Exponents (if any)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Now, let's solve the expression step by step:

1. 4 * 300 = 1200
2. 12 / 9 = 1.333333... (recurring decimal, rounded to 2 decimal places)
3. Perform multiplication before division (from left to right): 1200 - 1.33 ≈ 1198.67
4. Finally, add 3 to the result: 1198.67 + 3 ≈ 1201.67

So, the expression 4 * 300 - 12 / 9 + 3 is approximately equal to 1201.67.
